Probable transcription factor, required during migration of the gonadal distal tip cells (DTC) (PubMed:24811939). Probably regulates cell adhesion of DTCs via modulation of expression of genes involved in integrin-mediated adhesion, including tln-1, src-1, and integrin pat-2 (PubMed:24811939). Modulates expression of genes involved in protein trafficking during embryogenesis, including emo-1, sec-61, calu-1, sec-24.1, enpl-1, sar-1 and tfg-1 (PubMed:27510972). Expressed in the gonadal distal tip cells (DTC) during larval stages L2, L3 and L4. RNAi-mediated knockdown targeted to the gonadal distal tip cells (DTC) causes DTC migration defects (PubMed:24811939). Significant reduction in expression of src-1 and tln-1 in DTCs (PubMed:24811939). Causes slow growth after hatching (PubMed:27510972). Belongs to the bZIP family.
