lim-4 encodes a LIM homeodomain protein homologous to murine Lhx6 and L3/Lhx7, and to Drosophila ARROWHEAD; LIM-4 is required for differentiation of AWB chemosensory neurons, for several but not all aspects of RID motor neuron differentiation, expression of ser-2, repulsion from chemosensory repellants, SAA neurite outgrowth, and normal locomotion and head foraging; lim-4 is expressed in AWB, RID, RIV, RMDL, RMDR, RMEV, four SAA neurons, and four SIA neurons.
Enables DNA-binding transcription factor activity, RNA polymerase II-specific and RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Involved in several processes, including cell differentiation; positive regulation of transcription by RNA polymerase II; and serotonin biosynthetic process. Located in nucleus. Expressed in several structures, including ABalpppppa; head muscle; head neurons; lumbar neurons; and somatic nervous system. Is an ortholog of human LHX6 (LIM homeobox 6) and LHX8 (LIM homeobox 8).
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.
