forkhead associated (FHA) domain superfamily; Forkhead-associated (FHA) domains are small phosphopeptide recognition modules mostly found in eubacteria and eukaryotes. It is about 95-120 residues long that fold into an 11-stranded beta-sandwich. FHA domains can mediate the recognition of phosphorylated and non-phosphorylated substrates, as well as protein oligomerization. They specifically recognize threonine phosphorylation (pThr) accompanying activation of protein serine/threonine kinases. FHA domains show diverse ligand specificity. They may recognize the pTXXD motif, the pTXXI/L motif, and TQ clusters (singly and multiply phosphorylated). In eukaryotes, FHA superfamily members include forkhead-type transcription factors, as well as other signaling proteins, such as many regulatory proteins, kinases, phosphatases, motor proteins called kinesins, and metabolic enzymes. Many of them localize to the nucleus, where they participate in establishing or maintaining cell cycle checkpoints, DNA repair, or transcriptional regulation. FHA domains play important roles in human diseases, particularly in relation to DNA damage responses and cancers. In bacteria, FHA domain-containing proteins may participate in injection of viral proteins into host cells, transmembrane transporters, and cell division. FHA domain-containing proteins rarely include more than one copy of the domain. The only exception in eukaryotes is the checkpoint kinase Rad53 from Saccharomyces cerevisiae, which harbors two FHA domains (FHA1 and FHA2) flanking a central kinase domain. The two FHA domains recognize different phosphorylated targets and function independently from one another. In contrast, Mycobacterium tuberculosis ABC transporter Rv1747 contains two FHA domains but only one of them is essential for protein function.

Upon replacing ADP with ATP, a kinesin motor domain increases its affinity for microtubule binding and locks in place. Also, the neck linker binds to the motor domain, which repositions the other head domain through the coiled-coil domain close to a second tubulin dimer, about 80 Angstroms along the microtubule.

Kinesin motor domain, KIF22/Kid-like subgroup; Kinesin motor domain, KIF22/Kid-like subgroup. Members of this group might play a role in regulating chromosomal movement along microtubules in mitosis. This catalytic (head) domain has ATPase activity and belongs to the larger group of P-loop NTPases. Kinesins are microtubule-dependent molecular motors that play important roles in intracellular transport and in cell division. In most kinesins, the motor domain is found at the N-terminus (N-type). N-type kinesins are (+) end-directed motors, i.e. they transport cargo towards the (+) end of the microtubule. Kinesin motor domains hydrolyze ATP at a rate of about 80 per second, and move along the microtubule at a speed of about 6400 Angstroms per second. To achieve that, kinesin head groups work in pairs. Upon replacing ADP with ATP, a kinesin motor domain increases its affinity for microtubule binding and locks in place. Also, the neck linker binds to the motor domain, which repositions the other head domain through the coiled-coil domain close to a second tubulin dimer, about 80 Angstroms along the microtubule. Meanwhile, ATP hydrolysis takes place, and when the second head domain binds to the microtubule, the first domain again replaces ADP with ATP, triggering a conformational change that pulls the first domain forward.

forkhead associated (FHA) domain superfamily; Forkhead-associated (FHA) domains are small phosphopeptide recognition modules mostly found in eubacteria and eukaryotes. It is about 95-120 residues long that fold into an 11-stranded beta-sandwich. FHA domains can mediate the recognition of phosphorylated and non-phosphorylated substrates, as well as protein oligomerization. They specifically recognize threonine phosphorylation (pThr) accompanying activation of protein serine/threonine kinases. FHA domains show diverse ligand specificity. They may recognize the pTXXD motif, the pTXXI/L motif, and TQ clusters (singly and multiply phosphorylated). In eukaryotes, FHA superfamily members include forkhead-type transcription factors, as well as other signaling proteins, such as many regulatory proteins, kinases, phosphatases, motor proteins called kinesins, and metabolic enzymes. Many of them localize to the nucleus, where they participate in establishing or maintaining cell cycle checkpoints, DNA repair, or transcriptional regulation. FHA domains play important roles in human diseases, particularly in relation to DNA damage responses and cancers. In bacteria, FHA domain-containing proteins may participate in injection of viral proteins into host cells, transmembrane transporters, and cell division. FHA domain-containing proteins rarely include more than one copy of the domain. The only exception in eukaryotes is the checkpoint kinase Rad53 from Saccharomyces cerevisiae, which harbors two FHA domains (FHA1 and FHA2) flanking a central kinase domain. The two FHA domains recognize different phosphorylated targets and function independently from one another. In contrast, Mycobacterium tuberculosis ABC transporter Rv1747 contains two FHA domains but only one of them is essential for protein function.

forkhead associated (FHA) domain found in the kinesin-like protein KIF13 family; The KIF13 family includes KIF13A and KIF13B. KIF13A, also called kinesin-like protein RBKIN, is a plus end-directed microtubule-dependent motor protein involved in intracellular transport and in regulating various processes such as mannose-6-phosphate receptor (M6PR) transport to the plasma membrane, endosomal sorting during melanosome biogenesis, and cytokinesis. It mediates the transport of M6PR-containing vesicles from trans-Golgi network to the plasma membrane via direct interaction with the AP-1 complex. During melanosome maturation, KIF13A is required for delivering melanogenic enzymes from recycling endosomes to nascent melanosomes by creating peripheral recycling endosomal subdomains in melanocytes. It is also required for the abscission step in cytokinesis: it mediates translocation of ZFYVE26, and possibly TTC19, to the midbody during cytokinesis. KIF13B, also called kinesin-like protein GAKIN, is a novel kinesin-like protein that associates with the human homolog of the Drosophila discs large tumor suppressor in T lymphocytes. It is involved in reorganization of the cortical cytoskeleton. It regulates axon formation by promoting the formation of extra axons. KIF13B may be functionally important for the intracellular trafficking of membrane-associated guanylate kinase homologs (MAGUKs) and associated protein complexes. The FHA domain is a small phosphopeptide recognition module, but this group may lack the conserved residues that are required for binding phosphothreonine.

The START domain family belongs to the SRPBCC (START/RHO_alpha_C/PITP/Bet_v1/CoxG/CalC) domain superfamily of proteins that bind hydrophobic ligands. SRPBCC domains have a deep hydrophobic ligand-binding pocket. STARD4 plays an important role in steroidogenesis, trafficking cholesterol into mitochondria. It specifically binds cholesterol, and demonstrates limited binding to another sterol, 7a-hydroxycholesterol. STARD4 and STARD5 are ubiquitously expressed, with highest levels in liver and kidney. STRAD5 functions in the kidney within the proximal tubule cells where it is associated with the Endoplasmic Reticulum (ER), and may participate in ER-associated cholesterol transport. It binds cholesterol and 25-hydroxycholesterol. Expression of the gene encoding STARD5 is increased by ER stress, and its mRNA and protein levels are elevated in a type I diabetic mouse model of human diabetic nephropathy. STARD6 is expressed in male germ cells of normal rats, and in the steroidogenic Leydig cells of perinatal hypothyroid testes. It may play a pivotal role in the steroidogenesis as well as in the spermatogenesis of normal rats. STARD6 has also been detected in the rat nervous system, and may participate in neurosteroid synthesis.
