EpoR is thought to contribute to differentiation via multiple signaling pathways including the STAT5 pathway. Credit: Monkeyontheloose.

Although "the P3, P6 substitutions alter the conserved 'GATAAG' I box motif, a 'GATA' motif is present in the introduced EcoRV site. This introduced GATA sequence clearly does not serve as a functional I box [...]."[1]

"The I-box motif, 5'-GGATGAGATAAGA-3', or its shorter version 5'-GATAAG-3', has been found in the promoters of a large number of RBCS genes (Giuliano et al., 1988; Manzara and Gruissem, 1988). A related motif (the GATA box) is present in the promoters of the light-regulated chlorophyll a/b binding protein (CAB) genes of different species (Gidoni et al., 1989), and has been shown to be involved in the activation of an Arabidopsis CAB gene by light and by the circadian clock (Anderson and Kay, 1995). I-box and GATA binding factors have been identified in nuclear extracts from tobacco and tomato leaves and cotyledons (Borello et al., 1993; Giuliano et al., 1988; Manzara et al., 1991; Schindler and Cashmore, 1990). The I-box has therefore been suggested to be involved in light-regulated and/or leaf-specific gene expression of photosynthetic genes (Manzara et al., 1991), but to date no I-box binding protein has been cloned from plants."[2]

SRF is important during the development of the embryo, as it has been linked to the formation of mesoderm.[3][4]

The Serum response factor (SRF) has been shown to interact with GATA4.[5][6]

Cell specific developmental expression is tightly controlled, but, once expressed, require no additional activation -- GATA transcription factor (GATA), hepatocyte nuclear factors (HNF), PIT-1, MyoD, Myf5, Hox, winged-helix transcription factors.

The class of diverse Cys4 zinc fingers includes the family of GATA-factors.

In the diagram on the right, STAT5 may be involved with an erythropoiesis receptor, or Epo Receptor. Murine, members of the subfamily Murinae, Epo Receptor truncations and known functions are included. Erythroid differentiation depends on transcriptional regulator GATA1, zinc finger DNA binding domain binds specifically to DNA consensus sequence [AT]GATA[AG] promoter elements. In erythropoiesis, EpoR is best known for inducing survival of progenitors.
