Summary Information
Automatically generated summary See sections below for more information	The gene U2A is referred to in FlyBase by the symbol Dmel\U2A (CG1406, FBgn0033210). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: mRNA binding. There is experimental evidence that it is involved in the biological process: mitosis; mitotic spindle organization. 6 alleles are reported. The phenotype of these alleles is annotated with: mesothoracic tergum. It has one annotated transcript and one annotated polypeptide. Protein features are: Leucine-rich repeat; U2A'/phosphoprotein 32 family A, C-terminal. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of moderately high expression to a trough of low expression. Peak expression observed within 00-12 hour embryonic stages, in adult female stages. Summary of FlyAtlas Anatomical Expression Data: Expression at moderate levels in the following post-embryonic organs or tissues: larval central nervous system, adult ovary. Comments on Affy2 ProbeSet: ProbeSet 1631575_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of U2A. Gene sequence location is 2R:3562867..3563857.

Other Comments
	RNAi screen using dsRNA made from templates generated with primers directed against this gene results in a long metaphase spindle with misaligned chromosomes when assayed in S2 cells. This phenotype can be observed when the screen is performed with or without Cdc27 dsRNA. (Goshima et al., 2007) Mutants are embryonic lethal. (Nagengast et al., 2001) The gene products of U2A and snf are co-immunoprecipitated by antibodies to either protein, demonstrating that, like their yeast and human counterparts, they heterodimerize in vivo. A mutation in the U2A binding motif of snf reduces the amount of heterodimer formation but does not abolish it completely. The U2A binding motif from snf is only essential for heterodimer formation in the absence of the C-terminal end of the protein. The RNA binding specificity domain of snf is essential for interaction with U2A. The U2A gene product incorporation into U2 snRNP does not depend on dimerization of the U2A and snf gene products. (Nagengast and Salz, 2001) Homozygous U2A mutants complete embryogenesis but do not hatch. (Nagengast and Salz, 2001)
