CYP11A1 is also known as cytochrome P450C11A1, cytochrome P450scc and cytochrome P450, subfamily XIA. It is the first enzyme of all steroidogenic pathways, its elimination results in syndromes of steroid deficiency, including electrolyte imbalance, aberrant gene regulation, and suppression of male sex organ development(PMID: 12145347). Expression of CYP11A1 has been a useful tool for monitoring the differentiation state of cells from varius endocrine tissues. Identification of CYP11A1 expression by 13363-1-AP detected a ~45kd band in human placenta, with respect to the reported band at 49-52kd by Roby, et al and Durkee, et al. The murine 32-kDa isoform of Cyp11a1 is not produced by omission of the first ATG-containing exon (as is the case for human CYP11A1) but perhaps by alternative translational initiation(PMID:19342447).
