Description
Description: This gene encodes a calcium/calmodulin-dependent serine protein kinase. The encoded protein is a MAGUK (membrane-associated guanylate kinase) protein family member. These proteins are scaffold proteins and the encoded protein is located at synapses in the brain. Mutations in this gene are associated with FG syndrome 4, mental retardation and microcephaly with pontine and cerebellar hypoplasia, and a form of X-linked mental retardation. Multiple transcript variants encoding different isoforms have been found for this gene.
Function: Multidomain scaffolding protein with a role in synaptic transmembrane protein anchoring and ion channel trafficking. Contributes to neural development and regulation of gene expression via interaction with the transcription factor TBR1. Binds to cell-surface proteins, including amyloid precursor protein, neurexins and syndecans. May mediate a link between the extracellular matrix and the actin cytoskeleton via its interaction with syndecan and with the actin/spectrin-binding protein 4.1.
Subunit Structure: Binds WHRN and NRXN1 cytosolic tail. Interacts with CASKIN1, APBA1, LIN7(A/B/C) and L27 domain of DLG1 and isoform 2 of DLG4 (By similarity). CASK and LIN7 form two mutually exclusive tripartite complexes with APBA1 or CASKIN1 (By similarity). Interacts with FCHSD2. Interacts with TSPYL2. Part of a complex containing CASK, TBR1 and TSPYL2 (By similarity). Identified in a complex with ACTN4, IQGAP1, MAGI2, NPHS1, SPTAN1 and SPTBN1 (By similarity). Interacts with KIRREL3.
Similarity: The first L27 domain binds DLG1 and the second L27 domain probably binds LIN7.The protein kinase domain mediates the interaction with FCHSD2.In the N-terminal section; belongs to the protein kinase superfamily. CAMK Ser/Thr protein kinase family. CaMK subfamily. Belongs to the MAGUK family
