26587646 We conclude that cytochrome b5 can influence the electronic conductivity of cytochrome P450c17 via allosteric, protein-protein interactions.
25890314 CYB5A is the first RA susceptibility gene involved in androgen synthesis. Our functional analysis of SNP rs1790834 indicates that it contributes to the sex bias observed in RA.
25315771 Two acidic residues, Glu-48 and Glu-49, of cytochrome b5 are essential for stimulating the 17,20-lyase activity of CYP17A1.
25225034 Variants in CYB5A and CYB5R3 should be considered in the evaluation of breast cancer risk in African American women.
24832628 both area and ratio of 3betaHSD and CYB5A double positive cells, which could represent the hybrid cells of zona fasciculate and zona reticularis, are correlated with adrenal development and could influence age-related serum androstenedione levels.
24448000 raises the possibility that inhibition of CYB5A-deregulated downstream pathways, such as those involving TRAF6, may favor autophagy-mediated cancer cell death in selected subgroups of patients
24319746 Cytochrome b5 seems to play the key role in the formation of lipid-radical cycles in membranes.
24301457 Results define CYB5A as a novel prognostic factor for PDAC that exerts its tumor-suppressor function through autophagy induction and TRAF6 modulation.
24151200 CYB5A, which has a role in stearyl-CoA-desaturase activity, and RNF10, with an unknown role in weight regulating pathways, associated with adiposity and nominally increased the risk for T2D in American Indians.
23620596 CYP17A1/b5 interaction is stronger when the hydroxylase substrate pregnenolone is present in the CYP17A1 active site than when the lyase substrate 17alpha-hydroxypregnenolone is in the active site.
