<p>This subsection of the 'Pathology and Biotech' section describes the in vivo effects caused by ablation of the gene (or one or more transcripts) coding for the protein described in the entry.

Knockouts show increased susceptibility to infection with E.faecalis but not with P.aeruginosa, increased levels of H2O2 upon infection and a slightly shorter life span. Fertile animals show a bagging phenotype due to embryos being retained in the body and an increase of clec-60 mRNA levels upon infection. 50% of knockouts also have a dumpy phenotype. RNAi-mediated knockdown of the protein also results in higher susceptibility to infection by E.faecalis but not in a decreased life span or morphological changes.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.
