These phenotypic similarities suggest that these three proteins function in a common pathway important for establishing and maintaining apicobasal polarity in epithelial cells (1,2). Scribble contains many leucine-rich repeats and PDZ domains important for localizing scribble to adherens junctions and basolateral regions of mammalian epithelial cells (3). Scribble reportedly binds β-catenin, APC, E-cadherin and the E6 protein from high-risk virus type of HPV through a short motif important for E6-induced cell transformation (4-8). Overexpression of scribble inhibits transformation of rodent epithelial cells by HPV E6\/7 proteins (8). The phosphorylation state of Scribble has been shown to be functionally important, in part by regulating subcellular localization (9). Mass spectrometry studies have identified phosphorylation at Ser1220 as a frequent modification in a variety of cell and tissue types (10-13). The functional significance of this modification remains to be elucidated.\n\u003cb\u003eAlternate Names\u003c\/b\u003e\nCRIB1; hScrib; KIAA0147; LAP4; Protein LAP4; Protein scribble homolog; SCRB1; SCRIB; SCRIB1; Scribble; scribble planar cell polarity protein; scribbled homolog; scribbled homolog (Drosophila); scribbled planar cell polarity protein; VARTUL\n\n\u003cb\u003eSpecification\u003c\/b\u003e\n\nREACTIVITY: H M\nSENSITIVITY: Endogenous\nMW (kDa): 240\nSource\/Isotype: Rabbit IgG","brand":"CST","offers":[{"title":"Default Title","offer_id":46797570310313,"sku":"12316S","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/cst-12316s","provider":"Iright","version":"1.0","type":"link"}
