Inhibitor of apoptosis-promoting Bax1; Programmed cell-death involves a set of Bcl-2 family proteins, some of which inhibit apoptosis (Bcl-2 and Bcl-XL) and some of which promote it (Bax and Bak). Human Bax inhibitor, BI-1, is an evolutionarily conserved integral membrane protein containing multiple membrane-spanning segments predominantly localized to intracellular membranes. It has 6-7 membrane-spanning domains. The C termini of the mammalian BI-1 proteins are comprised of basic amino acids resembling some nuclear targeting sequences, but otherwise the predicted proteins lack motifs that suggest a function. As plant BI-1 appears to localize predominantly to the ER, we hypothesized that plant BI-1 could also regulate cell death triggered by ER stress. BI-1 appears to exert its effect through an interaction with calmodulin. The budding yeast member of this family has been found unexpectedly to encode a BH3 domain-containing protein (Ybh3p) that regulates the mitochondrial pathway of apoptosis in a phylogenetically conserved manner. Examination of the crystal structure of a bacterial member of this family shows that these proteins mediate a calcium leak across the membrane that is pH-dependent. Calcium homoeostasis balances passive calcium leak with active calcium uptake. The structure exists in a pore-closed and pore-open conformation, at pHs of 8 and 6 respectively, and the pore can be opened by intracrystalline transition; together these findings suggest that pH controls the conformational transition.

BAX inhibitor (BI)-1/YccA-like protein family; Mammalian members of the BAX inhibitor (BI)-1 like family of small transmembrane proteins have been shown to have an antiapoptotic effect either by stimulating the antiapoptotic function of Bcl-2, a well-characterized oncogene, or by inhibiting the proapoptotic effect of Bax, another member of the Bcl-2 family. Their broad tissue distribution and high degree of conservation suggests an important regulatory role. This superfamily also contains the lifeguard(LFG)-like proteins and other subfamilies which appear to be related by common descent and also function as inhibitors of apoptosis. In plants, BI-1 like proteins play a role in pathogen resistance. A prokaryotic member, Escherichia coli YccA, has been shown to interact with ATP-dependent protease FtsH, which degrades abnormal membrane proteins as part of a quality control mechanism to keep the integrity of biological membranes.

Golgi antiapoptotic protein; GAAP (or transmembrane BAX inhibitor motif containing 4) is a regulator of apoptosis that is related to the BAX inhibitor (BI)-1 like family of small transmembrane proteins, which have been shown to have an antiapoptotic effect either by stimulating the antiapoptotic function of Bcl-2, a well-characterized oncogene, or by inhibiting the proapoptotic effect of Bax, another member of the Bcl-2 family. Human GAAP has been linked to the modulation of intracellular fluxes of Ca(2+), by suppressing influx from the extracellular medium and reducing release from intracellular stores. A viral homolog (vaccinia virus vGAAP) acts similar to its human counterpart in inhibiting apoptosis.

Proteins similar to and including lifeguard (LFG), a putative regulator of apoptosis; Lifeguard (LFG) inhibits Fas-mediated apoptosis and interacts with the death receptor FasR/CD95/Apo1. LFG has been shown to interact with Bax and is supposed to be integral to cellular membranes such as the ER. A close homolog, PP1201 or RECS1, appears located in the Golgi compartment and also interacts with the Fas receptor CD95/Apo1. PP1201 is expressed in response to shear stress.
