CELE_C18A3.8, C18A3.8

hlh-14 encodes a basic helix-loop-helix (bHLH) transcription factor that is one of five C. elegans Achaete-Scute family homologs; HLH-14 activity is required generally for normal egg-laying, movement, body morphology, and larval development; more specifically, HLH-14 is required for proper neuronal development, particularly for regulation of the asymmetric cell division that gives rise to the PVQ/HSN/PHB neuroblasts and for normal differentiation of these neuroblast descendants, including their cell division patterns, migrations, and neurotransmitter expression; in specifying neuronal cell fates, genetic evidence suggests that hlh-14 acts together with hlh-2, which encodes the C. elegans E/Daughterless ortholog; HLH-14 is expresed exclusively in the embryo and detected in the left and right PVQ/HSN/PHB neuroblasts and their descendants, as well as in other cells identified, tentatively, as anterior neuroblasts and posterior neuroblasts such as Caapa.
