説明
Members of the Bcl-2 family play a major role in regulating the response of cells to a wide variety of apoptotic signals. Some Bcl-2 family members like Bcl-2, block apoptosis, whereas others promote apoptosis and inhibit Bcl-2 activity. Bcl-x is a Bcl-2 homologue that has two isoforms, resulting from alternative splicing. Bcl-xL (long) is a 241 amino acid protein (25-29 kDa) that is 47% homologous to Bcl-2 on the amino acid level. Bcl-xS (short) is a 178 amino acid protein (~ 19.5 kDa) lacking a 63 amino acid domain that is well conserved among members of the Bcl-2 protein family. Bcl-xL blocks cell death, whereas Bcl-xS inhibits Bcl-2 and promotes cell death.
The 2H12 antibody has been reported to recognize human, mouse and rat Bcl-xL (long) protein. An N-terminal peptide (amino acids 3-14) common to human and mouse Bcl-xL and Bcl-xS (short) proteins was used as the immunogen. Thus the antibody is also predicted to recognize the Bcl-xS protein as the sequence used for the immunogen is common to both Bcl-xL and Bcl-xS proteins. Reports from development, however, have indicated that Bcl-xS has not been observable.
