STAT4

A gene on chromosome 17q21.31 that encodes a member of the STAT family of transcription factors, which are phosphorylated by receptor-associated kinases in response to cytokines and growth factors, including IFNs, EGF, IL5, IL6, HGF, LIF and BMP2. The STAT4 protein product mediates responses to IL12 in lymphocytes, and regulates the differentiation of T helper cells.
