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>

Ceramide synthase that catalyzes formation of ceramide from sphinganine and acyl-CoA substrates, with high selectivity toward palmitoyl-CoA (hexadecanoyl-CoA; C16:0-CoA) as acyl donor (PubMed:12912983, PubMed:15823095, PubMed:16100120, PubMed:17977534, PubMed:17609214, PubMed:26853464). Can use other acyl donors, but with less efficiency (PubMed:15823095).6 Publications

Caution

According to a report, deletion of Cers5 protects from obesity: knockout mice are associated with reduced weight gain and improved systemic health after high fat diet challenge (PubMed:26853464). This result was however not confirmed by another study, which did not observe any protection from diet-induced obesity in knockout mice (PubMed:31150623). Effects observed in the first study might be indirect and caused by a large deletion that affects neighboring genes and/or deletes non-coding RNAs (PubMed:26853464, PubMed:31150623).2 Publications
Some prediction bioinformatics tools predict the presence of a homeobox domain (By similarity). However, the domain is degenerate and residues that are important for DNA-binding are absent (By similarity). Moreover, the protein localizes in the endoplasmic reticulum and not in the nucleus, strongly suggesting that it does not constitute a canonical homeobox domain (PubMed:12912983).Sequence analysis1 Publication
