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>

Thiol protease which shows activity against the fluorogenic substrate z-Arg-Arg-AMC.1 Publication

Miscellaneous

Mediates the radiation-induced bystander effect (RIBE), a process in which factors released by irradiated cells or tissues exert effects on unexposed cells or tissues. Following localized ultraviolet irradiation of the head, mediates RIBE in multiple unexposed regions including the posterior region. Also leads to RIBE including inhibition of cell death and increased embryonic lethality of progeny in unirradiated animals exposed to the culture medium of irradiated animals. Likely to exert RIBE by acting through the insulin-like receptor 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.
