Transcriptional activator that binds to DNA sequences containing the consensus pentanucleotide 5'-CGGA[AT]-3' (PubMed:1340465). Required for olfactory dopaminergic neuron differentiation; may directly activate expression of tyrosine hydroxylase (TH) (PubMed:19287374). Abundant in kidney (PubMed:1340465). Moderate levels seen in the heart, brain, lung, embryo and lower levels seen in spleen, intestine, testis and thymus (PubMed:1340465). Expressed in the dopaminergic neurons of the olfactory bulb at postnatal day 0 (at protein level). Sumoylated. Phosphorylated at Ser-191 and Ser-216 by RPS6KA1 and RPS6KA5; phosphorylation activates transcriptional activity. Significant reduction in the number of tyrosine hydroxylase (TH)-positive cells in the olfactory bulb. Belongs to the ETS family.
