CC -!- FUNCTION: The 3-beta-HSD enzymatic system plays a crucial role in the
CC biosynthesis of all classes of hormonal steroids. HSD VII is active
CC against four 7-alpha-hydroxylated sterols. Does not metabolize several
CC different C(19/21) steroids as substrates. Involved in bile acid
CC synthesis (PubMed:11067870). Plays a key role in cell positioning and
CC movement in lymphoid tissues by mediating degradation of 7-alpha,25-
CC dihydroxycholesterol (7-alpha,25-OHC): 7-alpha,25-OHC acts as a ligand
CC for the G protein-coupled receptor GPR183/EBI2, a chemotactic receptor
CC for a number of lymphoid cells (PubMed:22999953).
