Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome. This score <strong>cannot</strong> be used as a measure of the accuracy of the annotation as we cannot define the 'correct annotation' for any given protein.<p><a href='/help/annotation_score' target='_top'>More...</a></p>-Experimental evidence at protein leveli <p>This indicates the type of evidence that supports the existence of the protein.

Exhibits low testosterone 6-beta-hydroxylase activity.

Miscellaneous

Chimeric transcripts, characterized by CYP3A43 exon 1 joined at canonical splice sites to distinct sets of CYP3A4 or CYP3A5 exons, have been detected. All are possibly produced by trans-splicing. CYP3A43-CYP3A4 chimeric transcripts exist in 3 different combinations: CYP3A43 exon 1 joined in frame to CYP3A4 exons 2-13, CYP3A43 exon 1 joined in frame to CYP3A4 exons 4-13 and CYP3A43 exon 1 joined in frame to CYP3A4 exon 7-13. The longest chimeric isoform (CYP3A43 exon 1 joined to CYP3A4 exons 2-13) exhibits 6-beta-hydroxylase activity, while a shorter isoform (CYP3A43 exon 1 joined to CYP3A4 exons 4-13) does not. CYP3A43-CYP3A5 chimeric transcripts exist in 2 different combinations: CYP3A43 exon 1 joined in frame to CYP3A5 exon 11-13 and CYP3A43 exon 1 joined in frame to CYP3A5 exon 12-13. All chimeric transcripts are expressed at very low levels in the liver (PubMed:11726664).1 Publication

At protein level, three alleles are known: CYP3A43*1, CYP3A43*2 and CYP3A43*3. The sequence shown is that of CYP3A43*1, which is the most frequent allele. The allele CYP3A43*2 is likely to be non-functional.
