1.14.18.7 cytochrome b5 a Cb5-like domain (Cb5LD)-containing protein 746153 1.14.18.7 cytochrome b5 Arabidopsis thaliana FAH1 and FAH2 have no Cb5-like domain, and interact with electron transfer protein Cb5. Bax inhibitor-1 is a widely conserved cytoprotective protein localized in the endoplasmic reticulum membrane and also interacts with Cb5. Arabidopsis thaliana Bax inhibitor-1 -mediated suppression of cell death in yeast requires Saccharomyces cerevisiae fatty acid hydroxylase 1, which has a Cb5-like domain at the N terminus and interacts with Bax inhibitor-1 734909 1.14.18.7 cytochrome b5 fatty acid hydroxylase 1 has a Cb5-like domain at the N terminus and interacts with plant cryoprotective protein Bax inhibitor-1 734909
