Transcription factor (PubMed:17021039). Involved in negatively modulating apoptosis in germline and somatic cells, acting in partial redundancy with transcription factor egl-38/PAX5, probably by directly regulating transcription of apoptosis regulator ced-9 (PubMed:17021039). May bind to the DNA sequence motif 5'-GTAACG-3' in regulatory elements (PubMed:17021039).
