Species cross-reactivity is determined by western blot.
Applications Key: W=Western Blotting, IP=Immunoprecipitation, IF-IC=Immunofluorescence (Immunocytochemistry)
Specificity / Sensitivity
SAV1 (D6M6X) Rabbit mAb recognizes endogenous levels of total SAV1 protein.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to residues near the carboxy terminus of human SAV1 protein.
Western blot analysis of extracts from various cell lines using SAV1 (D6M6X) Rabbit mAb (upper) and β-Actin (D6A8) Rabbit mAb #8457 (lower).
Confocal immunofluorescent analysis of HCT 116 (higher expressing, left) and ACHN (lower expressing, right) cells using SAV1 (D6M6X) Rabbit mAb (green). Blue pseudocolor = DRAQ5® #4084 (fluorescent DNA dye).
Immunoprecipitation of SAV1 protein from A-204 cell extracts using Rabbit (DA1E) mAb IgG XP® Isotype Control #3900 (lane 2) or SAV1 (D6M6X) Rabbit mAb (lane 3). Lane 1 is 10% input. Western blot analysis was performed using SAV1 (D6M6X) Rabbit mAb.
Salvador homolog (SAV1), originally named WW45, was first identified as a 45 kDa protein containing a pair of WW domains and a coiled-coil region (1). SAV1 was subsequently shown to function as a scaffold protein, in a protein complex that includes the kinases MST2 and LATS1, and the transcriptional co-activator YAP (2). This protein complex comprises the core components of the Hippo signaling pathway, which regulates important cellular functions, including contact inhibition and apoptosis, that function to regulate tissue growth and organ size (3,4). A genetic screen in Drosophila identified a role for SAV1 in cell cycle regulation and apoptosis (5), while embryonic mice lacking Sav1 displayed hyperplastic growth and epithelial differentiation effects (6). These findings, together with the observation that SAV1 is mutated a number of human cancer cell lines, suggest that SAV1 functions as a tumor suppressor in the Hippo signaling pathway (5, 7).
