ETV3L is a transcription factor that appears to function as a retinoic acid (RA)-inducible repressor (Janesick et al., 2013).
Using in situ hybridization, Janesick et al. (2013) showed that RA receptor (RAR; see 180240) signaling induced neuronal differentiation and inhibited proproliferative neural markers in Xenopus embryos. Further analysis identified Erf (611888), Etv3 (164873), and Etv3l as RAR-responsive repressors expressed in neuroectoderm. Erf or Etv3/Etv3l knockdown inhibited the neural differentiation pathway and expanded expression of neural progenitor markers in Xenopus embryos. Moreover, knockdown of Erf or Etv3l promoted proliferation in the neural plate in Xenopus embryos, whereas Erf overexpression led to an increase of neurons.
Cao et al. (2018) characterized of the promoter region of LAIR1 (602992) and identified several ETS family members, including ETV3L, as enhancers of LAIR1 basic promoter activity. Ectopic expression in HO8910 ovarian cancer cells confirmed that ETV3L enhanced LAIR1 protein expression.
Gross (2025) mapped the ETV3L gene to chromosome 1q23.1 based on an alignment of the ETV3L sequence (GenBank NM_001004341) with the genomic sequence (GRCh38).
