Augmin complex subunit wac

Reviewed-Annotation score:

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. Note that the 'protein existence' evidence does not give information on the accuracy or correctness of the sequence(s) displayed.<p><a href='/help/protein_existence' target='_top'>More...</a></p>

<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

As part of the augmin complex, plays a role in centrosome-independent generation of spindle microtubules (PubMed:19289792).

The complex is required for mitotic spindle assembly through its involvement in localizing gamma-tubulin to spindle microtubules (PubMed:19289792).

wac is dispensable for somatic mitosis and for assembly of spindle microtubules in oocytes during female meiosis but is required during female meiosis for chromosome alignment and segregation (PubMed:19289792).

It is required for microtubule assembly near spindle poles in oocytes (PubMed:23785300).

It is also required for acentrosomal microtubule nucleation and meiotic spindle formation during male meiosis (PubMed:24829288).

wac binds to microtubules in vitro (PubMed:19289792).

Mutants are viable but have greatly reduced levels of augmin complex subunit Dgt2 (PubMed:19289792). Mitotic progression is delayed but is not blocked before anaphase onset and chromosomes are properly segregated (PubMed:19289792). 7% of meiotic chromosomes in spermatids are missegregated (PubMed:19289792). Mutant males are fertile but mutant females are sterile, developing fully mature ovaries but laying eggs that fail to hatch (PubMed:19289792). Chromosome positioning and segregation are disrupted in oocytes (PubMed:19289792). Chromosome spreading in oocytes following nuclear envelope breakdown is not limited as in wild-type and instead is spread along the spindle axis (PubMed:23785300). Significant increase in the frequency of oocyte spindles with a missing or weak spindle pole (PubMed:23785300). Delayed spindle formation in spermatocytes during male meiosis (PubMed:24829288).3 Publications

Component of the augmin complex composed of dgt2, dgt3, dgt4, dgt5, dgt6, msd1, msd5 and wac (PubMed:19289792, PubMed:19369198). The complex interacts directly or indirectly with microtubules and is required for centrosome-independent generation of spindle microtubules (PubMed:19289792). wac interacts directly (via coiled coil) with dgt2 (PubMed:19289792).

<p>The checksum is a form of redundancy check that is calculated from the sequence.
