Target

  • FunctionPlays a key role in steroid hormone synthesis by enhancing the metabolism of cholesterol into pregnenolone. Mediates the transfer of cholesterol from the outer mitochondrial membrane to the inner mitochondrial membrane where it is cleaved to pregnenolone.
  • Tissue specificityExpressed in gonads, adrenal cortex and kidney.
  • PathwaySteroid metabolism; cholesterol metabolism.
  • Involvement in diseaseDefects in STAR are the cause of adrenal hyperplasia type 1 (AH1) [MIM:201710]. The most severe form of adrenal hyperplasia. It is a condition characterized by onset of profound adrenocortical insufficiency shortly after birth, hyperpigmentation reflecting increased production of pro-opiomelanocortin, elevated plasma renin activity as a consequence of reduced aldosterone synthesis, and male pseudohermaphroditism resulting from deficient fetal testicular testosterone synthesis. Affected individuals are phenotypic females irrespective of gonadal sex, and frequently die in infancy if mineralocorticoid and glucocorticoid replacement are not instituted.

Thank you for contacting us.

This is not a phopspho specific antibody which means this antibody would detect total StAR protein i.e. phospho as well as non-phospho form. However it will not be able to distinguish between the two forms.

Indeed there are two entries in the Uniprot database, Q6IBK0 and P49675. Both are for the same protein. However the entry which is best to refer to is the P49675 as this is the entry which is manually annotated and curated (Swissprot). Indeed, Uniprot ...
