Description

Mouse Monoclonal Antibody

This RBCERNR monoclonal antibody recognizes human and mouse myeloid cell leukemia sequence 1 (Mcl-1) when phosphorylated on serine 159 (S159). Mcl-1 is an anti-apoptotic protein that is a member of the Bcl-2 family of proteins important for regulation of cell survival/apoptosis. Mcl-1 is primarily localized to the outer membrane of mitochondria where it prevents cytochrome c release via dimerization with other Bcl-2 family members such as Bim. PI3K activation of AKT results in the phosphorylation of GSK3 beta at serine 9 (S9) resulting in destabilization and degradation of GSK3 beta. Loss of GSK3 beta prevents phosphorylation of Mcl-1 on S159 and its subsequent ubiquitination and degradation. Mice conditionally lacking Mcl-1 in lymphocytes showed that Mcl-1 is essential during early lymphoid development and for the maintenance of mature lymphocytes. Applications Reported:This RBCERNR antibody has been reported for use in intracellular staining followed by flow cytometric analysis. Applications Tested: This RBCERNR antibody has been pre-titrated and tested by intracellular staining followed by flow cytometric analysis of normal human peripheral blood cells. This can be used at 5 μL (0.25 μg) per test. A test is defined as the amount (μg) of antibody that will stain a cell sample in a final volume of 100 μL. Cell number should be determined empirically but can range from 10^5 to 10^8 cells/test. Staining Protocol: Protocol A and Protocol C are recomm...

MCL1 (Myeloid cell leukemia-1) belongs to the Bcl-2 family and is involved in programing, differentiation and concomitant maintenance of cell viability, but not of proliferation. Isoform 1 of MCL1 inhibits apoptosis while isoform 2 promotes it. The carboxy terminal of MCL1 and bcl-2 share significant sequence homology. Expression of MCL1 is increased upon exposure of ML-1 cells to various types of DNA damaging agents (e.g. ionizing radiation, ultraviolet radiation, and alkylating drugs) along with increases in GADD45 and Bax and a decrease in bcl-2. Enhanced expression of MCL1, prominently associated with mitochondria, complements the continued expression of bcl-2 in ML-1 cells undergoing differentiation. Like bcl-2, MCL1 has the capacity to promote cell viability under conditions that otherwise cause apoptosis. While the mechanism by which MCL1 inhibits apoptosis is not known, it is thought that it may heterodimerize and neutralize pro-apoptotic members of the Bcl-2 family such as Bim or Bak. MCL1 was originally identified in differentiating myeloid cells, but has since been shown to be expressed in multiple cell types. MCL1 is essential for embryogenesis and for the development and maintenance of B and T lymphocytes in animals. MCL1 exists as at least two distinct isoforms designated MCL1L and MCL1S. In marked contrast to the larger isoform of MCL1, overexpression of MCL1S promotes cell death.
