Transcription factor NF-E2 45 kDa subunit (NFE2)

Component of the NF-E2 complex essential for regulating erythroid and megakaryocytic maturation and differentiation. Binds to the hypersensitive site 2 (HS2) of the beta-globin control region (LCR).

This subunit (NFE2) recognizes the TCAT/C sequence of the AP-1-like core palindrome present in a number of both erythroid and megakaryocytic gene promoters. Requires MAFK or other small MAF proteins for binding to the NF-E2 motif.
