Cyclin-dependent kinase 16

Gene

Cdk16

Organism
Mus musculus (Mouse)
Status
Reviewed-Annotation score: Annotation score: 5 out of 5-Experimental evidence at protein leveli

Functioni

Protein kinase that plays a role in vesicle-mediated transport processes and exocytosis. Can phosphorylate CCNY at 'Ser-336' (in vitro) (By similarity). Plays a role in the regulation of insulin secretion in response to changes in blood glucose levels. Regulates GH1 release by brain neurons. Phosphorylates NSF, and thereby regulates NSF oligomerization. Required for normal spermatogenesis. Regulates neuron differentiation and dendrite development.By similarity4 Publications

Interactioni

Subunit structurei

Found in a complex containing CABLES1, CDK17 and TDRD7. Interacts with BRSK2. Identified in a complex with NSF, syntaxin-1, synaptotagmin, SYN1, SYP and CDK5R1 (By similarity). Interacts with YWHAH, YWHAQ and YWHAZ. Interacts with CCNY; this increases the CDK16 kinase activity. Interacts with NSF.By similarity4 Publications
