[cc615] : Defects in M lineage fate specification, randomisation of division planes in the M lineage. Fate transformation of coelomocytes and bodywall muscles to sex myoblasts in the M lineage. Sex myoblast migration defect.
mls-2 encodes a homeodomain protein of the HMX family; during postembryonic development, MLS-2 is required for cell proliferation, cleavage orientation, and fate specification in the mesodermal M lineage; in regulating M lineage proliferation and fate specification, MLS-2 appears to act upstream of CYE-1/cyclin E and HLH-1/CeMyoD, respectively, the latter of which is not expressed in the M lineage in mls-2 mutant animals; MLS-2 is expressed in the nuclei of early proliferating undifferentiated M lineage cells (up to the 8-M stage), in a subset of head neurons, and in cells near the vulva during the L2 and L3 larval stages.
Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including establishment of mitotic spindle orientation; neuron differentiation involved in amphid sensory organ development; and regulation of cell differentiation. Located in nucleus. Expressed in several structures, including AB lineage cell; AWC-ON; M.dla; head; and somatic nervous system. Human ortholog(s) of this gene implicated in oculoauricular syndrome. Is an ortholog of human HMX1 (H6 family homeobox 1).
Map position created from combination of previous interpolated map position (based on known location of sequence) and allele information. Therefore this is not a genetic map position based on recombination frequencies or genetic experiments. This was done on advice of the CGC.
