What pLDDT means and how to read it

Function

Induces caspases and apoptosis. Counters the protective effect of BCL2

Subunit structure

Forms heterodimers either with the pro-apoptotic protein BAX or the anti-apoptotic protein BCL2 (PubMed:21183079). Interacts with PLEKHN1 (By similarity)

Subcellular location

Cytoplasm, Mitochondrion membrane, Mitochondrion outer membrane
