Protein Array - Anti-StAR antibody [STAR/2154] - BSA and Azide free (AB237908)

This data was produced with ab238057, the same antibody in a different formulation with BSA and Azide.
ab238057 was tested in protein array against over 19000 different full-length human proteins.
Z- and S- Score : The Z-score represents the strength of a signal that a monoclonal antibody (MAb) (in combination with a fluorescently-tagged anti-IgG secondary antibody) produces when binding to a particular protein on the HuProtTM array. Z-scores are described in units of standard deviations (SD's) above the mean value of all signals generated on that array. If targets on HuProtTM are arranged in descending order of the Z-score, the S-score is the difference (also in units of SD's) between the Z-score. S-score therefore represents the relative target specificity of a MAb to its intended target.
A MAb is specific to its intended target if the MAb has an S-score of at least 2.5. For example, if a MAb binds to protein X with a Z-score of 43 and to protein Y with a Z-score of 14, then the S-score for the binding of that MAb to protein X is equal to 29.

Supplementary information

The Steroidogenic Acute Regulatory protein (StAR) also known as STARD1 plays an important role in steroid hormone synthesis. It facilitates the transport of cholesterol from the outer to the inner mitochondrial membrane essential for steroid biosynthesis. StAR has a molecular mass of approximately 30 kDa. Expression of StAR occurs predominantly in steroidogenic tissues like adrenal glands ovaries and testes. The protein's efficient functioning is necessary for the maintenance of proper steroid hormone levels in the body.
Biological function summary

The transport activity of StAR is important for the production of steroid hormones which are pivotal in numerous physiological functions. StAR does not function alone; it forms a part of a larger complex of proteins involved in mitochondrial cholesterol transfer. By enabling the conversion of cholesterol to pregnenolone a precursor to various steroid hormones StAR directly affects processes such as metabolism immune function and sexual differentiation. Abnormalities in these processes can result from disruptions in StAR's activity.

Pathways

The involvement of StAR in cholesterol transport places it in the important steroidogenic pathway. This pathway includes interactions with other pivotal proteins such as cytochrome P450scc (CYP11A1) which further converts cholesterol into pregnenolone. Another important pathway where StAR participates is the adrenal biosynthesis pathway linking it to the production of glucocorticoids and mineralocorticoids. Disruption in these pathways due to StAR deficiency or malfunction can lead to severe biological implications.

StAR is closely associated with conditions like lipoid congenital adrenal hyperplasia (LCAH) and Addison's disease. Mutations or deficiencies in StAR can interrupt steroid hormone production which is essential for managing these conditions. Additionally proteins like CYP11A1 may show functional impairment in the presence of StAR mutations exacerbating these disorders. A deeper understanding of StAR's role in these conditions can support the development of targeted therapeutic strategies.
