Struct. Biol. 5:317-325(1998). CC -!- FUNCTION: Multidomain scaffolding protein with a role in synaptic CC transmembrane protein anchoring and ion channel trafficking. CC Contributes to neural development and regulation of gene CC expression via interaction with the transcription factor TRB1. CC Binds to cell-surface proteins, including amyloid precursor CC protein, neurexins and syndecans. May mediate a link between the CC extracellular matrix and the actin cytoskeleton via its CC interaction with syndecan and with the actin/spectrin-binding CC protein 4.1. CC -!- CATALYTIC ACTIVITY: ATP + a protein = ADP + a phosphoprotein. CC -!- COFACTOR: Magnesium (By similarity). CC -!- SUBUNIT: Binds WHRN and NRXN1 cytosolic tail. Interacts with CC CASKIN1, APBA1, LIN7(A/B/C) and L27 domain of DLG1 and isoform 2 CC of DLG4 (By similarity). CASK and LIN7 form two mutually exclusive CC tripartite complexes with APBA1 or CASKIN1 (By similarity). CC Interacts with FCHSD2. Interacts with TSPYL2.
