Tissue Specificity | Erythroid-specific. Only expressed in bone marrow and spleen. |
Post Translational Modifications | Acetylated.can be acetylated on both Lys-270 and Lys-288. Acetylation on Lys-270 (by CBP) appears to be the major site affecting EKLF transactivation activity. Sumoylated.sumoylation, promoted by PIAS1, leads to repression of megakaryocyte differentiation. Also promotes the interaction with the CDH4 subunit of the NuRD repression complex. Phosphorylated primarily on serine residues in the transactivation domain. Phosphorylation on Thr-23 is critical for the transactivation activity. |
Function | Transcription regulator of erythrocyte development. Binds to the CACCC box in the beta-globin gene promoter and activates transcription. Probably serves as a general switch factor for erythroid development. When sumoylated, acts as a transcriptional repressor by promoting interaction with CDH2/MI2beta and also represses megakaryocytic differentiation. |
