Gene name:
Mpp5(Pals1);
Protein name:
MAGUK p55 subfamily member 5;
Alternative:
Protein associated with Lin-7 1;
Organism:
Mouse (Mus musculus).
General Annotation
Sub Unit:
Heterodimer with MPP1. Interacts with MPP7. Forms a complex with CRB1 and MPP4. Component of a complex whose core is composed of ARHGAP17, AMOT, MPP5/PALS1, INADL/PATJ and PARD3/PAR3 (By similarity). Interacts with CRB3, EZR, INADL, LIN7C, MPDZ, PARD6B and SC6A1.
Function:
May play a role in tight junctions biogenesis and in the establishment of cell polarity in epithelial cells. May modulate SC6A1/GAT1-mediated GABA uptake by stabilizing the transporter. Required for localization of EZR to the apical membrane of parietal cells and may play a role in the dynamic remodeling of the apical cytoskeleton.
Subcellular Location:
Cell membrane
Peripheral membrane protein
Endomembrane system
Peripheral membrane protein
Cell junction
tight junction
Localized to the tight junctions of epithelial cells and a subset of intracellular vesicles. Localized to the Purkinje cell body and axon. Localized to apical membrane domains of the outer limiting membrane junctions in the retina. Colocalizes with MPP1 in the retina at the outer limiting membrane (OLM).
