Protein attributes

Sequence length	172 AA.
Sequence status	Complete.
Protein existence	Evidence at protein level

General annotation (Comments)

Function	Retards apoptosis induced by IL-3 deprivation. May function in the response of hemopoietic cells to external signals and in maintaining endothelial survival during infection.
Subunit structure	Interacts directly with BCL2L11/BIM By similarity. Interacts directly with BAK1, BID, BMF and BBC3.
Subcellular location	Cytoplasm.
Tissue specificity	Expressed in hemopoietic tissues, including bone marrow, spleen and thymus.
Induction	By granulocyte-macrophage colony-stimulating factor and LPS in macrophages.
Sequence similarities	Belongs to the Bcl-2 family.
