Transcriptional activator (PubMed:19307308, PubMed:31552090). Regulates the positioning of motor neurons within the lateral medial column of the spinal cord and controls the terminal arborization of specific motor neuron axons within their target muscles (By similarity). Required for the expression of CDH8 and SEMA3E in ETV4- expressing motor neurons and for the exclusion of CDH7 expression from these neurons (By similarity). May play a role in keratinocyte differentiation (PubMed:31552090). {ECO:0000250|UniProtKB:P28322, ECO:0000269|PubMed:19307308, ECO:0000269|PubMed:31552090}. (Microbial infection) Binds to the enhancer of the adenovirus E1A gene and acts as a transcriptional activator; the core-binding sequence is 5'-[AC]GGA[AT]GT-3'. . This is the function of Ensembl gene identifier ENSG00000175832 (ETV4, ETS variant transcription factor 4).
