Transcription factor that specifically binds to the octamer motif (5'-ATTTGCAT-3') (PubMed:2904654, PubMed:7859290). Regulates IL6 expression in B cells with POU2AF1 (By similarity). Regulates transcription in a number of tissues in addition to activating immunoglobulin gene expression (PubMed:2901913, PubMed:2904654). Modulates transcription transactivation by NR3C1, AR and PGR (PubMed:10480874). Activates the U2 small nuclear RNA (snRNA) promoter. Transactivation activity is enhanced by transcriptional coactivator POU2AF1. Interacts with NR3C1, AR and PGR (PubMed:10480874). Interacts with POU2AF1; the interaction increases POU2F2 transactivation activity (PubMed:7859290). Isoform 3 is B-cell specific. Isoform 5 is expressed in B-cells and the immunoglobulin-expressing T-cell line MOLT-4, but not in the T-cell line BW5147. Incomplete sequence. Belongs to the POU transcription factor family. Class-2 subfamily. Truncated N-terminus.
