Model confidence (pLDDT)

The mean pLDDT of this model is 71.9 (confident overall). pLDDT is AlphaFold's per-residue confidence score from 0 to 100. In MolViewer, choose the B-factor color scheme to color the model by pLDDT, because AlphaFold stores it in the B-factor column.

What pLDDT means and how to read it

Function

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

Subunit structure

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 interaction increases the CDK16 kinase activity (By similarity). Interacts with CCNYL1; this interaction mutually increases the stability of CDK16 and…
