ID:SCRIB_HUMAN DESCRIPTION: RecName: Full=Protein scribble homolog; Short=Scribble; Short=hScrib; AltName: Full=Protein LAP4; 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. INTERACTION: P27361:MAPK3; NbExp=2; IntAct=EBI-357345, EBI-73995; 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. 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.
The RNAfold program from the Vienna RNA Package is used to perform the secondary structure predictions and folding calculations. The estimated folding energy is in kcal/mol. The more negative the energy, the more secondary structure the RNA is likely to have.

The pictures above may be empty if there is no ModBase structure for the protein. The ModBase structure frequently covers just a fragment of the protein. You may be asked to log onto ModBase the first time you click on the pictures. It is simplest after logging in to just click on the picture again to get to the specific info on that model.
Orthologous Genes in Other Species
Orthologies between human, mouse, and rat are computed by taking the best BLASTP hit, and filtering out non-syntenic hits. For more distant species reciprocal-best BLASTP hits are used. Note that the absence of an ortholog in the table below may reflect incomplete annotations in the other species rather than a true absence of the orthologous gene.
