Product Overview

Description	Recombinant Human MOB Kinase Activator 1A is produced by our E.coli expression system and the target gene encoding Ser2-Arg216 is expressed with a 6His tag at the C-terminus.
Accession	Q9H8S9
Synonym	MOB Kinase Activator 1A; Mob1 Alpha; Mob1A; Mob1 Homolog 1B; Mps One Binder Kinase Activator-like 1B; MOB1A; C2orf6; MOB4B; MOBK1B; MOBKL1B
Gene Background	MOB Kinase Activator 1A (MOB1A) belongs to the MOB1/phocein family, which acts as an activator of LATS1/2 in the Hippo signaling pathway, plays a key role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. MOBKL1B stimulates the kinase activity of STK38 and STK38L. MOBKL1B binds to and regulate downstream targets such as the NDR-family protein kinases and LATS1 kinase.

Target Details

Target Function	Activator of LATS1/2 in the Hippo signaling pathway which plays a pivotal role in organ size control and tumor suppression by restricting proliferation and promoting apoptosis. The core of this pathway is composed of a kinase cascade wherein STK3/MST2 and STK4/MST1, in complex with its regulatory protein SAV1, phosphorylates and activates LATS1/2 in complex with its regulatory protein MOB1, which in turn phosphorylates and inactivates YAP1 oncoprotein and WWTR1/TAZ. Phosphorylation of YAP1 by LATS1/2 inhibits its translocation into the nucleus to regulate cellular genes important for cell proliferation, cell death, and cell migration. Stimulates the kinase activity of STK38 and STK38L. Acts cooperatively with STK3/MST2 to activate STK38.
Protein Families	MOB1/phocein family
Database References	HGNC: 16015 OMIM: 609281 KEGG: hsa:55233 STRING: 9606.ENSP00000379364 UniGene: PMID: 28675297 Through a comprehensive set of biochemical, biophysical, mutational and structural studies, we quantitatively assess how phosphorylation of MOB1A regulates its interaction with both MST kinases and LATS/NDR family kinases in vitro. PMID: 28373297 In this study, we investigated the mechanisms behind the recruitment of MST1 and MST2 kinases to MOB1, which facilitate signal transmission in the Hippo pathway by bringing the MST1 and MST2 kinases in close vicinity to their substrates, the LATS family kinases. PMID: 28373298 MOB1 binds differently to the NDR2 and LATS1 kinases.MOB1 interaction with Hippo and MST protein is not essential for development and tissue growth control. PMID: 28947795 No relationship has been found between the MOBKL1B-NS5A interaction and hepatitis C virus replication. PMID: 25031347 The RING ligase praja2 ubiquitylates and degrades Mob, a core component of NDR/LATS kinase and a positive regulator of the tumour-suppressor Hippo cascade. PMID: 23652010 Mob1A and Mob1B are needed for cell abscission and centriole re-joining after telophase and cytokinesis. PMID: 22454515 Results suggest that Mob1 and the other mammalian orthologues of the mitotic exit network regulate mitotic progression by facilitating the timely mobilization of the chromosomal passenger complex to the spindle midzone. PMID: 19955215 hMOB1A and hMOB1B are 2 LATS-binding proteins that may function as tumor suppressors in human cancer cells. PMID: 19739119 Mats1 can rescue the lethality associated with loss of Mats function in Drosophila; As Mats1 is mutated in human tumors, Mats-mediated growth inhibition and tumor suppression is likely conserved in humans PMID: 15766530 MATS1 mRNA expression is suppressed in tumor tissue and its low expression is associated with tumor growth, invasion and metastasis of colorectal cancer PMID: 17611689

Proteins are sensitive to heat, and freeze-drying can preserve the activity of the majority of proteins. It improves protein stability, extends storage time, and reduces shipping costs. However, freeze-drying can also lead to the loss of the active portion of the protein and cause aggregation and denaturation issues. Nonetheless, these adverse effects can be minimized by incorporating protective agents such as stabilizers, additives, and excipients, and by carefully controlling various lyophilization conditions.

Commonly used protectant include saccharides, polyols, polymers, surfactants, some proteins and amino acids etc. We usually add 8% (mass ratio by volume) of trehalose and mannitol as lyoprotectant. Trehalose can significantly prevent the alter of the protein secondary structure, the extension and aggregation of proteins during freeze-drying process; mannitol is also a universal applied protectant and fillers, which can reduce the aggregation of certain proteins after lyophilization.

Our protein products do not contain carrier protein or other additives (such as bovine serum albumin (BSA), human serum albumin (HSA) and sucrose, etc., and when lyophilized with the solution with the lowest salt content, they often cannot form A white grid structure, but a small amount of protein is deposited in the tube during the freeze-drying process, forming a thin or invisible transparent protein layer.

Reminder: Before opening the tube cap, we recommend that you quickly centrifuge for 20-30 seconds in a small centrifuge, so that the protein attached to the tube cap or the tube wall can be aggregated at the bottom of the tube. Our quality control procedures ensure that each tube contains the correct amount of protein, and although sometimes you can't see the protein powder, the amount of protein in the tube is still very precise.
