Species predicted to react based on 100% sequence homology: Xenopus, Horse.
Specificity / Sensitivity
Phospho-MOB1 (Thr12) (D2E3) Rabbit mAb recognizes endogenous levels of MOB1 protein only when phosphorylated at Thr12.
Source / Purification
Monoclonal antibody is produced by immunizing animals with a synthetic phosphopeptide corresponding to residues surrounding Thr12 of human MOB1 protein.
Western blot analysis of extracts from MCF7 cells, untreated or H2O2-treated (2.5 mM, 30 min), using Phospho-MOB1 (Thr12) (D2E3) Rabbit mAb (upper) and MOB1 Antibody #3863 (lower).
MOB1 was first identified in yeast as a protein that binds to Mps with essential roles in the completion of mitosis and the maintenance of ploidy (1). Its Drosophila and mammalian homologs, Mats and MOB1, respectively, are involved in the Hippo signaling tumor suppressor pathway, which plays a critical role in organ size regulation and which has been implicated in cancer development (2-5). There are two MOB1 proteins in humans, MOB1α and MOB1β, that are encoded by two different genes but which have >95% amino acid sequence identity (6). Both forms bind to members of the nuclear Dbf2-related (NDR) kinases, such as LATS1/2 and NDR1/2, thereby stimulating kinase activity (7-9). This binding is promoted by the phosphorylation of MOB1 at several threonine residues by MST1 and/or MST2 (5,10).
Phosphorylation at Thr12 by MST1/2 stabilizes MOB1, enhancing its binding and regulation of LATS1 (5). The resultant increase in LATS1 kinase activity promotes inhibitory phosphorylation of the transcriptional co-activators YAP and TAZ (11,12), leading to changes in the expression of genes involved in cell cycle progression (13).
