Automatically generated summary

See sections below for more information
The gene male-specific lethal 3 is referred to in FlyBase by the symbol Dmel\msl-3 (CG8631, FBgn0002775). It is a protein_coding_gene from Drosophila melanogaster. There is experimental evidence that it has the molecular function: chromatin binding; methylated histone residue binding. There is experimental evidence that it is involved in the biological process: dosage compensation. 33 alleles are reported. No phenotypic data is available. It has 2 annotated transcripts and 2 annotated polypeptides. Protein features are: Chromo domain-like; Chromo domain/shadow; MRG. Summary of modENCODE Temporal Expression Profile: Temporal profile ranges from a peak of high expression to a trough of low expression. Peak expression observed within 00-06 hour embryonic stages. Summary of FlyAtlas Anatomical Expression Data: Two or more Affy2 ProbeSets identify exons of this gene. This is a summary of the tissue expression peaks exhibited in at least one of these ProbeSets. Expression at moderate levels in the following post-embryonic organs or tissues: larval central nervous system, adult crop, adult hindgut, adult salivary gland, adult ovary, larval carcass. Gene sequence location is 3L:7116310..7118623.

mle3
Homozygous males exhibit delayed development; survive as larvae for ten days. Ten-day-old male larvae have small undeveloped imaginal discs, which, however, when transplanted into wild type larvae are capable of undergoing nearly complete (wing, leg) or partial (eye-antenna) differentiation; few homozygous mle gynandromorphs survive; XO patches small, with small bristles, and mostly confined to abdomen [Uenoyama, Uchida, Fukunaga, and Oishi, 1982, Genetics 102: 223-31(fig.)]. No interaction with mle. Females transformed into phenotypic males (tra, tra2) or intersexes (dsx) unaffected by mle3, i.e. mle3 acts only upon single-X-bearing flies. Females heterozygous for SxlF1 and homozygous (and to a lesser extent heterozygous) for mle3 show signs of intersexual development; effect less severe when mothers homozygous for mle3 [Uenoyama, Fukunaga, and Oishi, 1982, Genetics 102: 233-43 (fig.)]. Staining of polytene X chromosome of mle3 males similar to that of mle males (Lucchesi, Skripsky, and Tax, 1982, Genetics 100: s42; Okuno, Satou, and Oishi, 1984, Jpn. J. Genet. 59: 237-47).

Comments
The putative 481aa msl-3 protein is predicted from the sequence of one cDNA which represents a transcript generated by alternative splicing. The encoded protein has three unique amino-terminal amino acids and is colinear with the longer msl-3 protein from amino acid 35 of the 512aa protein on. A protein of the expected size has not been detected in larvae by western blots.
Antibodies were made to regions common to both of the predicted msl-3 proteins.

Gene products of the male specific lethal (msl) group of genes preferentially associate with the male X chromosome and may have a role in dosage compensation. This may be achieved by regulating an inverse dosage effect, which would be maintained on the male X and nullified on the autosomes.
Gene products of the male specific lethal (msl) group of genes including msl-1, msl-2, msl-3, mle, and mof are associated with all female chromosomes at a low level but are sequestered to the X chromosome in males. There is evidence for the presence of nucleation sites for association of msl proteins with the X chromosome rather than individual gene binding sites.
mof colocalises with the MSL complex on the X chromosome: a sequence of binding events results in the formation of the MSL complex on the X chromosome in males and in the targeting of mof to its presumed site of action.
msl-2 and msl-1 colocalise to a reproducible subset of their wild-type X chromosome sites in the absence of either mle or msl-3.
Male-specific lethal (MSL) proteins accumulate in a subregion of male nuclei (the X chromosome) beginning at late blastoderm stage. X chromosomal binding of the MSLs is observed throughout embryonic and larval development in both diploid and polytene tissues. His4 colocalises with the MSLs in embryos. Binding of the MSLs is interdependent in diploid cells and is prevented in female embryonic cells by Sxl.
Sex- and chromosome-specific binding of the male-specific lethal (msl) proteins occurs in Drosophilid species spanning 4 genera. msl binding correlates with the evolution of the sex chromosomes.
The products of msl-1, msl-2, mle and msl-3 loci specifically associate with hundreds of sites along the X chromosome in males, but not in females. The binding of each of the four proteins requires the functional products from the other three. 2X3A individuals are mosaic for both Sxl expression and msl-1, msl-2, mle and msl-3 binding to the X chromosome, with a perfect inverse correlation at the cellular level between Sxl expression and msl-1, msl-2, mle and msl-3 X chromosome binding.
Immunostaining of embryonic and larval stages demonstrates that His4, msl-1 and msl-3 are associated with the male X chromosome as early as gastrulation, while mle binding is not detected until the late embryonic/late larval stages.
The msl-3, mle and msl-1 gene products may associate with one another in a male-specific heteromeric complex on the X chromosome to achieve its hyperactivation.
Elements needed for dosage compensation are localised to the X chromosome only after blastoderm and msl-dependent dosage compensation is not necessary during the first part of embryogenesis. This suggest the existance of an additional msl-independent dosage compensation mechanism; dosage compensation of run expression at blastoderm is not dependent on male specific lethal genes.
The msl-2 primary transcript may play a role in male-specific binding of mle, msl-3 and msl-1 to the X chromosome.
Association of H4Ac16 protein with the male X chromosome requires wild type function of msl-1, msl-2, mle and msl-3.
The four msl gene products interact to form a multiprotein complex.
The X chromosome binding of mle requires wild type msl-1, msl-2 and msl-3 functions.
Mutants are defective for dosage compensation in males. Homozygous males exhibit delayed development; survive as larvae for ten days. Ten-day-old male larvae have small undeveloped imaginal discs, which, however, when transplanted into wild type larvae are capable of undergoing nearly complete (wing, leg) or partial (eye-antenna) differentiation. Mutants show no interaction with mle1. Females transformed into phenotypic males (tra1, tra21) or intersexes (dsx1) are unaffected by msl-31, i.e. msl-31 acts only upon single-X-bearing flies.
Staining of polytene X chromosome of msl-3 males similar to that of mle males.
Few homozygous msl-32 gynandromorphs survive; X0 patches small, with small bristles and mostly confined to abdomen.
