Clone Host Grade Applications
Polyclonal Rabbit Affinity Purified B
The signal transducer and activator of transcription (STAT) family of transcription factors is composed of seven family members (STATs 1, 2, 3, 4, 5A, 5B and 6) that are involved in many cell processes (apoptosis, anti-apoptosis, cell differentiation and proliferation) depending upon the cell type. STATs are activated by ligand binding of mostly cytokine receptors, that receptor associating with a Janus kinase (JAK) family member that phosphorylates a STAT protein, causing it to translocate to the nucleus, where it can bind to DNA and regulate the transcription of particular genes. Phosphorylation on serine 727 by ERK1&2, JNK, or MSK1, together with phosphorylation of tyrosine 705 by JAK1&2, is required for maximum transcriptional activity.
