This Mouse ACVR2A overexpression lysate was created in HEK293 Cells and intented for use as a Western blot (WB) positive control. Purification of ACVR2A protein (Cat: 50613-M08H) from the overexpression lysate was verified.
A DNA sequence encoding the extracellular domain of mouse ACVR2A (NP_031422.3) (Met 1-Pro 134) was expressed, with a C-terminal polyhistidine tag.
The secreted recombinant mouse ACVR2A comprises 126 amino acids and has a calculated molecular mass of 14.8 kDa. As a result of glycosylation, the recombinant protein migrates as an approximately 35 kDa band in SDS-PAGE under reducing conditions.
Mouse ACVR2A HEK293 Overexpression Lysate: 使用指南
Cell lysate was prepared by homogenization of the over-expressed cells in ice-cold modified RIPA Lysis Buffer with cocktail of protease inhibitors (Sigma). Cell debris was removed by centrifugation. Protein concentration was determined by Bradford assay (Bio-Rad protein assay, Microplate Standard assay). The cell lysate was boiled for 5 min in 1 x SDS loading buffer (50 mM Tris-HCl pH 6.8, 12.5% glycerol, 1% sodium dodecylsulfate, 0.01% bromophenol blue) containing 5% b-mercaptoethanol, and lyophilized.
ACVR2A and ACVR2B are two activin type II receptors. ACVR2A has been shown to interact with INHBA, SYNJ2BP and ACVR1B. The bovine ACVR2A gene encodes a protein of 513 amino acids which is highly homologous (approximately 98% identity) to the rat, mouse, and human ACVR2A proteins. Inactivation of ACVR2A is a common event in prostate cancer cells suggesting it may play an important role in the development of prostate cancer. The ACVR2A gene is a putative tumor suppressor gene that is frequently mutated in microsatellite-unstable colon cancers (MSI-H colon cancers). Frameshift mutation of ACVR2A may contribute to MSI-H colon tumorigenesis via disruption of alternate TGF-beta effector pathways.
