...Imre Gaspar; Janos Szabad Kavar 21g , a dominant female-sterile mutation of Drosophila , identifies the α Tubulin67C gene that encodes α4-tubulin, the maternally provided α-tubulin isoform. Although α4-tubulin is synthesized during oogenesis, its function is required only in the early cleavage...

...Zsolt Venkei; Imre Gáspár; Gábor Tóth; János Szabad Although α4-tubulin comprises only about one-fifth of the α-tubulin pool in every Drosophila egg, in the absence of α4-tubulin - in eggs of the kavar 0 /- hemizygous females - only a tassel of short microtubules forms with two barely...

...-specific α-tubulin, enhance meiotic nondisjunction and zygotic loss of ncd D , a partial loss-of-function mutant of ncd . The enhancement is dominant and allele-specific with respect to αTub67C , and depends on the recessive effects of ncd D . Cytologically, embryos of αTub67C/+ show delayed meiotic...

...Alistair Harrison; Howard Stebbings; Jeremy S. Hyams ABSTRACT Usage of the tyrosinated, detyrosinated and acetylated forms of α-tubulin in ovarian nutritive tube microtubules of the hemipterans Oncopeltus fasciatus and Notonecta glauca glauca was investigated by immunofluorescence microscopy...
