MOB3A/B/C antibody detects MOB kinase activator 3A, 3B, and 3C, a conserved family of adaptor proteins that function as key regulators of Hippo signaling, cell polarity, and apoptotic control. Encoded by three closely related genesMOB3A, MOB3B, and MOB3Cthese proteins belong to the MOB (Mps one binder) family, which serve as phosphorylation-dependent scaffolds that link upstream kinases to their downstream effectors in multiple signaling pathways. MOB3 family members share strong sequence conservation and overlapping functions in maintaining tissue architecture, controlling cell proliferation, and coordinating responses to cellular stress.
MOB3A/B/C proteins are small, approximately 25 kilodaltons each, and are characterized by a conserved MOB domain that mediates interactions with serine/threonine kinases of the NDR and LATS families. Through these interactions, MOB3 proteins modulate kinase activation, subcellular localization, and substrate specificity, ensuring tight regulation of the Hippo pathway that governs cell growth and apoptosis. By binding to MST1 (STK4), MOB3A/B/C proteins also influence apoptosis by promoting caspase activation and stress-induced cell death.
The MOB3A/B/C antibody is widely used in cell signaling, cancer biology, and developmental research to investigate adaptor-mediated kinase regulation and signal transduction dynamics. Western blot analysis detects multiple closely migrating bands around 25 kilodaltons corresponding to MOB3A, MOB3B, and MOB3C, while immunofluorescence reveals predominantly cytoplasmic localization with enrichment at the plasma membrane and perinuclear regions. This antibody is a valuable reagent for characterizing how MOB3 family proteins integrate kinase signaling with cell polarity and cytoskeletal control.
Functionally, MOB3 proteins act as regulatory scaffolds that promote or inhibit kinase cascades depending on cellular context. In the Hippo pathway, they interact with core kinases such as LATS1/2 and MST1/2, affecting downstream transcriptional regulators YAP and TAZ. Beyond Hippo signaling, MOB3 family members influence other cellular networks, including MAPK and apoptotic pathways, linking extracellular cues to transcriptional and structural outcomes. Dysregulation of MOB3 expression has been associated with oncogenesis, particularly in liver, colorectal, and pancreatic cancers, where altered MOB3 levels disturb growth control and apoptosis balance.
At the molecular level, MOB3A/B/C proteins undergo post-translational modifications, including phosphorylation and ubiquitination, that fine-tune their adaptor functions. MOB3A has been shown to bind MST1 and inhibit its pro-apoptotic signaling, while MOB3B and MOB3C may modulate this interaction to preserve mitochondrial integrity. These opposing roles underscore the complex regulatory balance maintained by the MOB3 family in coordinating survival and cell death pathways. The MOB3A/B/C antibody provides a robust approach for monitoring these interactions and assessing the contribution of each isoform to kinase network regulation.
In developmental systems, MOB3 proteins participate in epithelial tissue patterning and organ growth through modulation of cell junction integrity and polarity establishment. Their expression is tightly controlled during embryogenesis and tissue regeneration. Deficiency or imbalance in MOB3 activity leads to deregulated proliferation and impaired tissue architecture, highlighting their importance in maintaining cellular organization. The MOB3A/B/C antibody allows precise detection of these proteins in both developmental and disease contexts, supporting mechanistic studies of Hippo pathway control and kinase cross-talk.
In disease models, overexpression of MOB3A or MOB3B correlates with tumor progression and reduced apoptosis, while loss of MOB3C expression may enhance susceptibility to cellular stress. Their dual natureas tumor suppressors or promoters depending on signaling balancemakes them central nodes in cancer signaling networks. Using the MOB3A/B/C antibody, researchers can track changes in expression, post-translational modification, and subcellular distribution that define these divergent outcomes.
NSJ Bioreagents provides a rigorously validated MOB3A/B/C antibody optimized for western blotting, immunohistochemistry, and immunofluorescence. Its sensitivity and specificity make it ideal for studying Hippo pathway dynamics, kinase regulation, and cell polarity mechanisms across diverse cell types and conditions. This antibody supports high-confidence analysis of MOB3 family function in normal physiology, developmental signaling, and oncogenic transformation.
Optimal dilution of the MOB3A/B/C antibody should be determined by the researcher.
E.coli-derived human MOB3A/B/C recombinant protein (Position: E30-H217) was used as the immunogen for the MOB3A/B/C antibody.
After reconstitution, the MOB3A/B/C antibody can be stored for up to one month at 4oC. For long-term, aliquot and store at -20oC. Avoid repeated freezing and thawing.
