Summary: Enables actin binding activity and cyclin-dependent protein serine/threonine kinase activator activity. Acts upstream of or within nervous system development; positive regulation of calcium ion-dependent exocytosis; and positive regulation of protein kinase activity. Located in cytoplasm. Is active in presynapse. Is expressed in several structures, including nervous system and retina. Orthologous to human CDK5R2 (cyclin dependent kinase 5 regulatory subunit 2).

Title: Peripheral and orofacial pain sensation is unaffected by the loss of p39.
In this study, we discovered that selective upregulation of p39 is the underlying mechanism that accommodates the increased functional requirement of Cdk5 activation during neuronal differentiation. In addition, we demonstrated that p39 selectively directs Cdk5 to phosphorylate protein substrates essential for axonal development, dendritic spine formation, and synaptogenesis. Moreover, our studies suggest opposing roles o

These data suggest p35 and p39 have specific and overlapping roles in oligodendrocyte development, some of which may be independent of Cdk5 activation.

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.
