The gene Actin 42A is referred to in FlyBase by the symbol Dmel\Act42A (CG12051, FBgn0000043). It is a protein_coding_gene from Drosophila melanogaster. Based on sequence similarity, it is predicted to have molecular function: structural constituent of cytoskeleton. There is experimental evidence that it is involved in the biological process: cytokinesis; phagocytosis, engulfment. 10 alleles are reported. The phenotypes of these alleles are annotated with: mesothoracic tergum; trichogen cell. It has one annotated transcript and one annotated polypeptide. Protein features are: Actin, conserved site; Actin-related protein; Actin/actin-like conserved site. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of very high expression to a trough of high expression. Peak expression observed at stages throughout embryogenesis, during late larval stages, at stages throughout the pupal period, in stages of adults of both sexes. Summary of FlyAtlas Anatomical Expression Data: Nearly all larval and adult organs/tissues expressed at moderate or high levels. Expression at high levels in the following post-embryonic organs or tissues: larval central nervous system, larval/adult midgut, larval/adult hindgut, larval Malpighian tubules, adult heart, larval fat body, larval salivary gland, larval trachea, adult ovary, adult male reproductive system, larval carcass. Expression at moderate levels in the following post-embryonic organs or tissues: adult head, adult central nervous system, adult crop, adult Malpighian tubules, adult salivary gland, adult spermathecae, adult carcass. Comments on Affy2 ProbeSet: ProbeSet 1624471_s_at completely aligns to an exonic region of the only FlyBase-annotated transcript isoform of Act42A. Gene sequence location is 2R:1901415..1903194.

Act42A
Codes for cytoplasmic actin; transcribed throughout
development; one of two actin genes transcribed in Kc cells
and several other cell lines (Fyrberg, Mahaffy, Bond, and
Davidson, 1983, Cell 33: 115-23). One of three actin genes
expressed in the wing disc during wing development, each with
its characteristic profile. Peak expression at 44h of pupal
age, little or no expression at 60h rising again at 80h. 44h
peak corresponds to time of maximum change in cell shape
(Peterson, Bond, Mitchell, and Davidson, 1985, Dev. Genet.
5: 219-25).

Act42A transcripts are most abundant in embryos. They are evenly distributed in preblastoderm embryos, becoming localized to the periphery at blastoderm formation. Later they are observed in the brain and ventral nerve cord as well as in the developing gonad, proventriculus, and midgut.

cDNA Clones ( 155 )
Please Note
This section lists
cDNAs and ESTs that fall within the genomic extent
of the gene model, which may include cDNAs and ESTs
of genes within introns, or of overlapping genes.
Please see GBrowse for alignment of the cDNAs and ESTs
to the gene model.
In a sample of 79 genes with multiple introns, 33 showed significant heterogeneity in G+C content among introns of the same gene and significant positive correspondence between the intron and the third codon position G+C content within genes. These results are consistent with selection adding against preferred codons at the start of genes.
The expression of HIS-C genes during oogenesis has been studied, and compared to periods of DNA synthesis and actin expression during this developmental stage.
Codes for cytoplasmic actin; transcribed throughout development; one of two actin genes transcribed in Kc cells and several other cell lines (FBrf0038990). One of three actin genes expressed in the wing disc during wing development, each with its characteristic profile. Peak expression at 44h of pupal age, little or no expression at 60h rising again at 80h. 44h peak corresponds to time of maximum change in cell shape (FBrf0042391). Transcription increased 6-8 fold by 20-OH-ecdysone in tissue culture cells (FBrf0047102; FBrf0064343).
