Organism
Mycobacterium tuberculosis (strain ATCC 25618 / H37Rv)
Status
Reviewed-Annotation score:

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. Note that the ‘protein existence’ evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

Prevents aggregation of substrate proteins and promotes their refolding (PubMed:15327959).1 Publication
Recombinant extracellular protein activates expression of NF-kappa-B in immortalized human dermal endothelial cells in a TLR4-dependent, TLR2-independent manner. Activation occurs via MYD88-dependent and -independent pathways and requires TIRAP, TRIF, TRAM and MD-2 (some experiments done in mouse cells, mice do not usually catch tuberculosis) (PubMed:15809303).1 Publication

Miscellaneous

Purified 65 kDa antigen can elicit a strong delayed-type hypersensitivity reaction in experimental animals infected with M.tuberculosis. This protein is one of the major immunoreactive proteins of the mycobacteria (PubMed:3029018). It contains epitopes that are common to various species of mycobacteria (PubMed:7699930).2 Publications

<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:iFF034616F709DA2A
