pregnan-21-ol dehydrogenase (NADP+) activity

Catalysis of the reaction: NADP+ + pregnan-21-ol = H+ + NADPH + pregnan-21-al.

pregnan-21-ol dehydrogenase (NAD+) activity

Catalysis of the reaction: NAD+ + pregnan-21-ol = H+ + NADH + pregnan-21-al.

steroid 21-monooxygenase activity

Catalysis of the reaction: A C(21) steroid + [reduced NADPH--hemoprotein reductase] + O2 = a 21-hydroxy-C(21)-steroid + [oxidized NADPH--hemoprotein reductase] + H2O.

interleukin-21 binding

Binding to interleukin-21.

21-deoxycortisol binding

Binding to 21-deoxycortisol.

interleukin-21 receptor binding

Binding to an interleukin-21 receptor.

chemokine (C-C motif) ligand 21 binding

DRM complex

A transcriptional repressor complex that contains the lin-9, lin-35, lin-37, lin-52, lin-53, lin-5is involved in 4-, dpl-1 and efl-1 proteins, and is involved in cell fate specification.

cortisol O-acetyltransferase activity

Catalysis of the reaction: acetyl-CoA + cortisol = CoA + cortisol 21-acetate.

regulation of interleukin-21 production

Any process that modulates the frequency, rate, or extent of interleukin-21 production.
