Q14160

FUNCTION: Scaffold protein involved in different aspects of polarized cells differentiation regulating epithelial and neuronal morphogenesis. Most probably functions in the establishment of apico-basal cell polarity. May function in cell proliferation regulating progression from G1 to S phase and as a positive regulator of apoptosis for instance during acinar morphogenesis of the mammary epithelium. May also function in cell migration and adhesion and hence regulate cell invasion through MAPK signaling. May play a role in exocytosis and in the targeting synaptic vesicles to synapses. Functions as an activator of Rac GTPase activity. SUBUNIT: Interacts (via PDZ domains) with VANGL2. Interacts with CTNNB1 and MAPK12 (By similarity). Interacts with UBE3A and HPV E6. Interacts with PAK1 and PAK2. Interacts with ARHGEF7 and GIT1; interacts directly with ARHGEF7. Interacts (via PDZ domains) with LPP and TRIP6; the interaction is direct. Interacts (via PDZ domains) with TJP2. Interacts (via PDZ domains) with APC; may mediate APC targeting to adherens junctions of epithelial cells. Interacts (via PDZ domains) with TSHR; regulates TSHR trafficking and function. Interacts with MCC. Interacts (via fourth PDZ domain) with tick-borne encephalitis virus NS5 protein; this interaction inhibits SCRIB and downstream STAT1 phosphorylation, thereby preventing activation of JAK-STAT signaling pathway. SUBCELLULAR LOCATION: Cell membrane; Peripheral membrane protein. Cell junction, adherens junction. Cytoplasm. Note=Targeting to cell-cell junctions which is CDH1-dependent is required for the pro-apoptotic activity. Localizes to neuronal post- and pre- synaptic regions. ALTERNATIVE PRODUCTS: Event=Alternative splicing; Named isoforms=3; Name=1; IsoId=Q14160-1; Sequence=Displayed; Name=2; Synonyms=Variant N1; IsoId=Q14160-2; Sequence=VSP_010906; Note=No experimental confirmation available; Name=3; IsoId=Q14160-3; Sequence=VSP_010908; TISSUE SPECIFICITY: Expressed in kidney, skeletal muscles, liver, lung, breast, intestine, placenta and skin mainly in epithelial cells (at protein level). PTM: Ubiquitinated; targeted for UBE3A-dependent multiubiquitination in the presence of high-risk HPV E6 proteins and degraded. DISEASE: Defects in SCRIB are a cause of neural tube defects (NTD) [MIM:182940]. NTD are congenital malformations of the central nervous system and adjacent structures related to defective neural tube closure during the first trimester of pregnancy. Failure of neural tube closure can occur at any level of the embryonic axis. Common NTD forms include anencephaly, myelomeningocele and spina bifida, which result from the failure of fusion in the cranial and spinal region of the neural tube. NTDs have a multifactorial etiology encompassing both genetic and environmental components. SIMILARITY: Belongs to the LAP (LRR and PDZ) protein family. SIMILARITY: Contains 16 LRR (leucine-rich) repeats. SIMILARITY: Contains 4 PDZ (DHR) domains. GENE SYNONYMS:SCRIB CRIB1 KIAA0147 LAP4 SCRB1 VARTUL.
