Annotation score:3 out of 5

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

Catalyzes the acylation of sphingosine to form ceramides. Exhibits substrate preference for fatty acyl-coA chains containing 20 and 22 carbons. Required for adaptation of the nematode to anoxia. Anoxia tolerance may require one or more of the ceramide species that are either specifically or preferentially synthesized by hyl-2, and seems to be effected by a pathway that is parallel to that involving daf-2.1 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.
