BNIP-2- like (BNIPL), also known as Bcl-2/adenovirus E1B 19 kDa interacting protein 2-like, is a apaptosis-associated protein that shares 72% homology with BNIP-2. BNIPL is highly expressed in human placenta and lung. There are two alternative splices: BNIPL-1 and BNIPL-2. Both BNIPL-1 and BNIPL-2 have a conserved arginine-patch motif in Rho protein family. BNIPL-1 has function in suppressing cell growth through binding to MIF (macrophage migration inhibitory factor) and GFER (growth factor erv1(saccharomyces cerevisiae)-like). BNIPL-2 may suppress the Cdc42GAP’s activity through ineracting with Cdc42GAP. BNIPL-2, containg a key BCH domain, which may induce the cell pseudopod growth, takes part in modulating cell migrations. Thus it suggested BNIPL-2 implicated in cell migration progresses and tumor translocation.
