Sp2 transcription factor

Transcription factor Sp2 is a is_associated_with::protein that in humans is encoded by the SP2 is_associated_with::gene.

Function
This gene encodes a member of the Sp subfamily of Sp/XKLF transcription factors. Sp family proteins are sequence-specific DNA-binding proteins characterized by an amino-terminal trans-activation domain and three carboxy-terminal zinc finger motifs. This protein contains the least conserved DNA-binding domain within the Sp subfamily of proteins, and its DNA sequence specificity differs from the other Sp proteins. It localizes primarily within subnuclear foci associated with the nuclear matrix, and can activate or in some cases repress expression from different promoters.

Interactions
Sp2 transcription factor has been shown to interact with is_associated_with::E2F1.
