Protein

Protein lin-7 homolog C

Gene

LIN7C

Organism
Homo sapiens (Human)
Status
Reviewed - Annotation score: 5 out of 5- Experimental evidence at protein leveli

Functioni

Plays a role in establishing and maintaining the asymmetric distribution of channels and receptors at the plasma membrane of polarized cells. Forms membrane-associated multiprotein complexes that may regulate delivery and recycling of proteins to the correct membrane domains. The tripartite complex composed of LIN7 (LIN7A, LIN7B or LIN7C), CASK and APBA1 may have the potential to couple synaptic vesicle exocytosis to cell adhesion in brain. Ensures the proper localization of GRIN2B (subunit 2B of the NMDA receptor) to neuronal postsynaptic density and may function in localizing synaptic vesicles at synapses where it is recruited by beta-catenin and cadherin. Required to localize Kir2 channels, GABA transporter (SLC6A12) and EGFR/ERBB1, ERBB2, ERBB3 and ERBB4 to the basolateral membrane of epithelial cells.

Interactioni

Subunit structurei

Forms two exclusive ternary complexes with CASK and APBA1 or CASKIN1 (By similarity). Can also interact with other modular proteins containing protein-protein interaction domains like MPP5, MPP6, MPP7, DLG1, DLG2 and DLG3 through its L27 domain. Interacts with DLG4 and GRIN2B as well as CDH1 and CTNNB1, the channels KCNJ12/Kir2.2, KCNJ4/Kir2.3 and probably KCNJ2/Kir2.1 and SLC6A12/BGT-1 via its PDZ domain. The association of LIN7A with cadherin and beta-catenin is calcium-dependent, occurs at synaptic junctions and requires the actin cytoskeleton. Interacts with EGFR, ERBB2, ERBB3 and ERBB4 with both PDZ and KID domains. Associates with KIF17 via APBA1. Interacts with HTR4 (By similarity). Forms a tripartite complex composed of DLG1, MPP7 and LIN7 (LIN7A or LIN7C). Interacts with MAPK12 (By similarity).By similarity
