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.

A potent antigen in animals immunized with live bacteria, it induces a strong delayed-type hypersensitivity (DTH) in immunized animals (PubMed:10531201). Elicits a mostly Th1 type of T-cell response in healthy humans; induces IFN-gamma production from CD4+ and CD8+ cells (PubMed:12654810). Functions as an adhesin, binds to mouse macrophages via mannose residues (PubMed:10531201, PubMed:25359607). Might interact via host CD209 (PubMed:16092920).4 Publications

Glycosylated, with mannose residues (PubMed:8626314, PubMed:10542234, PubMed:10531201, PubMed:25359607). The secreted protein has from 0 to 9 mannose residues, the majority have 6, 7, or 8 mannose residues (22, 24 and 17% respectively) (PubMed:10531201). Deglycosylated molecules had a significantly lower capacity to elicit a DTH reaction in guinea pigs in vivo or to activate specific T lymphocytes in vitro (PubMed:10531201). Pretreating mouse macrophages with mannan decreases binding of M.tuberculosis (PubMed:25359607). The non-glycosylated form stimulates IFN-gamma production however, so glycosylation is not essential (PubMed:12654810).1 Publication4 Publications
Runs as 45 and 47 kDa protein, the nature of the difference between the 2 forms is not known but is still seen after alpha-mannosidase treatment (PubMed:10531201).1 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. The algorithm is described in the ISO 3309 standard. </p> <p class="publication">Press W.H., Flannery B.P., Teukolsky S.A. and Vetterling W.T.<br /> <strong>Cyclic redundancy and other checksums</strong><br /> <a href="http://www.nrbook.com/b/bookcpdf.php">Numerical recipes in C 2nd ed., pp896-902, Cambridge University Press (1993)</a>)</p> Checksum:i59E5D0455A997BED
