Summary
Enables protein serine/threonine kinase activity. Involved in neural precursor cell proliferation and positive regulation of apoptotic process. Acts upstream of or within intrinsic apoptotic signaling pathway in response to oxidative stress. Located in cytoplasm. Is expressed in several structures, including alimentary system; central nervous system; early conceptus; genitourinary system; and sensory organ. Orthologous to human MELK (maternal embryonic leucine zipper kinase). [provided by Alliance of Genome Resources, Apr 2022]
Expression
Biased expression in CNS E11.5 (RPKM 14.4), placenta adult (RPKM 9.4) and 14 other tissues See more

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.
