Annotation score:5 out of 5

<p>The annotation score provides a heuristic measure of the annotation content of a UniProtKB entry or proteome.

<p>This section provides any useful information about the protein, mostly biological knowledge.<p><a href='/help/function_section' target='_top'>More...</a></p>Functioni

Major component of the type IV pilus (T4P) that plays a role in cellular adherence, microcolony formation, resistance to neutrophil mediated killing, twitching motility as well as transformation (PubMed:27213957).

Mediates the attachment and the formation of bacterial microcolonies on host epithelial cells. Mechanistically, pili retractation induces host NF-kappa-B activation in infected cells, which is temporally associated with the formation of gonococcal microcolonies (PubMed:27213957).

Caution

In PubMed:413571 it is said that 50% of the peptides have N-methyl-Phe and 50% begin with Thr-9. N-terminal methylation produces preview during Edman degradation, which makes this appear to happen when the peptide is completely N-terminal methylated.Curated

The O-linked glycan identified as Gal-GlcNAc disaccharide in PubMed:7477282 and PubMed:10048019 is now identified as either a hexosyl-diacetamidotrideoxyhexoside (DATDHex) by mass spectrometry in PubMed:15249686, or alpha-D-galactopyranosyl-(1->3)-2,4-diacetamido-2,4-dideoxy-beta-D-glucopyranoside (DADDGlc) by X-ray diffraction in PubMed:16949362. It is not clear whether there is a chemical difference in the glycosylation of the two derivatives of strain MS11 used in these experiments, or not.2 Publications
In some MS11 derivative strains, Ser-75 is modified to O-(2-aminoethylphosphoryl)serine, and in some other derivatives that can be secondarily modified to O-(2-cholinephosphoryl)serine by N-methylation.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.
