Gene type: protein coding
RefSeq status: REVIEWED
Organism: Homo sapiens
Lineage: Eukaryota; Metazoa; Chordata; Craniata; Vertebrata; Euteleostomi; Mammalia; Eutheria; Euarchontoglires; Primates; Haplorrhini; Catarrhini; Hominidae; Homo
Also known as: P39; NCK5AI; p39nck5ai
Summary: The protein encoded by this gene is a neuron-specific activator of CDK5 kinase. It associates with CDK5 to form an active kinase. This protein and neuron-specific CDK5 activator CDK5R1/p39NCK5A both share limited similarity to cyclins, and thus may define a distinct family of cyclin-dependent kinase activating proteins.

What's a GeneRIF?

a biomarker consisting of the phosphorylation of the retinoblastoma protein (Rb) on serine 249 combined with elevated p39 expression. This biomarker correlates with epithelial-to-mesenchymal transition traits in non-small cell lung carcinoma (NSCLC) cells.

p39 is essential for recruiting scaffolding protein muskelin to stress fibers.
Title: The Cdk5 activator P39 specifically links muskelin to myosin II and regulates stress fiber formation and actin organization in lens.

Hepatocellular carcinoma patients with lower p39 expression had poorer overall survival rate than that with high expression.
Title: Decreased expression of p39 is associated with a poor prognosis in human hepatocellular carcinoma.
both proteasomal degradation and calpain cleavage of p35 and p39 are stimulated by membrane association, which is in turn mediated via myristoylation of their p10 regions.
Title: Membrane association facilitates degradation and cleavage of the cyclin-dependent kinase 5 activators p35 and p39.
Our data suggest that neurotoxic insults lead to calpain-mediated conversion of p39 to p29, which might contribute to deregulation of Cdk5

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.
