Tree Number(s): D12.644.360.075.718.937; D12.776.476.075.718.875
Unique ID: D051020
RDF Unique Identifier: http://id.nlm.nih.gov/mesh/D051020
Annotation: do not confuse with the closely related BCL2-ASSOCIATED X PROTEIN
Scope Note: A member of the bcl-2 protein family that plays a role in the regulation of APOPTOSIS and is a regulatory subunit for PROTEIN PHOSPHATASE 1. Two major isoforms of the protein exist due to ALTERNATIVE SPLICING of the BCL2L1 mRNA and are referred to as Bcl-XS and Bcl-XL.
Entry Term(s): bcl-X(L) Protein; bcl-X(S) Protein; bcl-XL Protein; bcl-XS Protein; bcl-Xa Protein; bcl-Xalpha Protein; bcl-Xb Protein; bcl-Xbeta Protein; bcl-Xlong Protein; bcl-Xshort Protein; bcl-x(beta) Protein; bcl2-Like 1 Protein; bcl2L1 Protein
