STAT1alpha (Signal transducer and activator of transcription 1 alpha) is a 91kD protein belonging to the transcription factor STAT family. Members of the STAT family respond to cytokines and growth factors and are phosphorylated by receptor associated kinase to form homo- or hetro-dimers. These then translocate to the cell nucleus to act as transcription activators. STAT1 is activated by a number of different ligands including the IFN, gp130 and receptor tyrosine kinase families. STAT1 has two different forms, a 91kD form (STAT1alpha) and an 84kD form (STAT1beta), This antibody is specific for the 91kD form, STAT1alpha and does not react with STAT1beta.
