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.

Isoform 1: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc and 4-methylumbelliferone-GlcNAc as substrates but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro) (PubMed:11148210). Does not bind acetyl-CoA and does not have histone acetyltransferase activity (PubMed:24088714).5 Publications
Isoform 3: Cleaves GlcNAc but not GalNAc from O-glycosylated proteins. Can use p-nitrophenyl-beta-GlcNAc as substrate but not p-nitrophenyl-beta-GalNAc or p-nitrophenyl-alpha-GlcNAc (in vitro), but has about six times lower specific activity than isoform 1.1 Publication

Caution

The mouse and rat orthologs were initially identified as bi-functional proteins containing an N-terminal domain with O-GlcNAcase activity and a C-terminal domain with histone acetyltransferase activity. The histone acetyltransferase activity was detected only when the protein was expressed in mammalian cells, but not when expressed in bacterial cells, suggesting that the histone acetyltransferase activity might be due to the presence of a contaminant. Comparison of the human protein with a bacterial putative acetyltransferase (AC Q2CEE2) shows that the residues important for acetyl-CoA binding are not conserved, and that the residues proposed to be important for histone acetyltransferase activity are not in a position where they could participate in catalysis. Characterization of the human protein shows that it does not bind acetyl-CoA and therefore cannot have acetyltransferase activity.1 Publication1 Publication

<p>The checksum is a form of redundancy check that is calculated from the sequence. It is useful for tracking sequence updates.</p> <p>It should be noted that while, in theory, two different sequences could have the same checksum value, the likelihood that this would happen is extremely low.</p> <p>However UniProtKB may contain entries with identical sequences in case of multiple genes (paralogs).</p> <p>The checksum is computed as the sequence 64-bit Cyclic Redundancy Check value (CRC64) using the generator polynomial: x<sup>64</sup> + x<sup>4</sup> + x<sup>3</sup> + x + 1.
