Summary: Enables DNA-binding transcription activator activity, RNA polymerase II-specific and RNA polymerase II cis-regulatory region sequence-specific DNA binding activity. Involved in nervous system development; positive regulation of macromolecule biosynthetic process; and regulation of dendrite morphogenesis. Located in nucleus. Is expressed in several structures, including adult optic lobe neurons; adult uniglomerular antennal lobe projection neuron lPN; epithelium; ganglia; and gut section. Human ortholog(s) of this gene implicated in X-linked deafness 2. Orthologous to several human genes including POU3F4 (POU class 3 homeobox 4). [provided by Alliance of Genome Resources, Dec 2024]

Grh and Vvl participate in a regulatory network controlling epithelial maturation.
Title: Genome-wide identification of Grainy head targets in Drosophila reveals regulatory interactions with the POU domain transcription factor Vvl.
Vvl is highly expressed in the prothoracic gland during embryogenesis and is enriched in the gland during larval development, suggesting that Vvl might function as a master transcriptional regulator in this tissue.
Title: Transcriptional control of steroid biosynthesis genes in the Drosophila prothoracic gland by ventral veins lacking and knirps.
Dfr/Vvl is highly expressed in a range of immunocompetent tissues, including the male ejaculatory duct, where its presence overlaps with and drives the expression of cecropin
