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.

<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

Component of the elongator complex which is required for multiple tRNA modifications, including mcm5U (5-methoxycarbonylmethyl uridine), mcm5s2U (5-methoxycarbonylmethyl-2-thiouridine), and ncm5U (5-carbamoylmethyl uridine) (PubMed:15769872).

The elongator complex catalyzes formation of carboxymethyluridine in the wobble base at position 34 in tRNAs (PubMed:29332244).

It functions as a gamma-toxin target (TOT); disruption of the complex confers resistance to Kluyveromyces lactis toxin zymocin (pGKL1 killer toxin) (PubMed:11296232).

May also be involved in sensitivity to Pichia inositovora toxin.

Caution

The elongator complex was originally thought to play a role in transcription elongation. However, it is no longer thought to play a direct role in this process and its primary function is thought to be in tRNA modification.4 Publications

Component of the elongator complex, which consists of ELP1/IKI3, ELP2, ELP3, ELP4, ELP5/IKI1 and ELP6 (PubMed:11435442, PubMed:11390369, PubMed:11689709, PubMed:27974378, PubMed:27872205). The elongator complex is composed of two copies of the Elp123 subcomplex (composed of ELP1/IKI3, ELP2 and ELP3) and two copies of the Elp456 subcomplex (composed of ELP4, ELP5/IKI1 and ELP6) (PubMed:27974378, PubMed:27872205). The Elp123 subcomplex forms a two-lobed scaffold, which binds the Elp456 subcomplex asymmetrically (PubMed:27974378, PubMed:27872205). In each lobe, ELP2 is tightly sandwiched between ELP1/IKI3 and ELP3 (PubMed:31309145). The Elp123 subcomplex binds tRNA through ELP1/IKI3 and ELP3 and can bind 2 tRNAs simultaneously (PubMed:31309145). tRNA-binding by the Elp123 subcomplex induces conformational rearrangements which precisely position the targeted anticodon base in the active site (PubMed:31309145). The Elp456 subcomplex binds tRNA and has ATPase activity (PubMed:22556426, PubMed:22343726).

<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.
