Cask Gene Summary [Rat]
Enables PDZ domain binding activity; neurexin family protein binding activity; and protein kinase C binding activity. Involved in several processes, including positive regulation of dendritic spine morphogenesis; positive regulation of insulin secretion; and protein localization to plasma membrane. Located in several cellular components, including apical dendrite; basolateral plasma membrane; and podocyte foot. Part of protein-containing complex. Is active in glutamatergic synapse; postsynaptic density, intracellular component; and presynapse. Human ortholog(s) of this gene implicated in FG syndrome and syndromic X-linked intellectual disability Najm type. Orthologous to human CASK (calcium/calmodulin dependent serine protein kinase).

Protein Domains
A protein domain is a distinct structural or functional region within a protein that can evolve, function, and exist independently of the rest of the protein chain. These domains in rat Cask often fold into stable, three-dimensional structures and are associated with specific biological functions, such as binding to DNA, other proteins, or small molecules.
