Enables RNA polymerase II transcription regulatory region sequence-specific DNA binding activity. Acts upstream of or within several processes, including determination of adult lifespan; epithelial cell maturation; and negative regulation of transcription by RNA polymerase II. Located in cytoplasm; membrane; and nucleus. Is expressed in early conceptus; genitourinary system; heart; and limb. Orthologous to human TFCP2L1 (transcription factor CP2 like 1).
