Specific protein 1 (Sp1) is a transcription regulator that has a transactivation domain at the N-terminus and a DNA-binding domain at the C-terminus, that contain three zinc fingers (ZF). It belongs to transcription factor family and is located on chromosome 12q13.
Peptide sequence around phosphorylation site of threonine 739 (T-A-Tp-P-S), according to the protein NP_612482.2

Immunohistochemistry (1 paper)
Anti-phospho-SP1 (pThr739) antibody has been used in immunohistochemistry.
Specific protein 1 (Sp1) controls the up- and down-regulation of hCtr1 (human high-affinity copper transporter 1). It controls the expression of several genes that participates in differentiation, cell cycle and oncogenesis. It has the ability to bind GC/GT‐rich promoter elements with the help of C(2)H(2)‐type zinc fingers at the C‐terminal domain.

Transcription factor that can activate or repress transcription in response to physiological and pathological stimuli. Binds with high affinity to GC-rich motifs and regulates the expression of a large number of genes involved in a variety of processes such as cell growth, apoptosis, differentiation and immune responses. Highly regulated by post-translational modifications (phosphorylations, sumoylation, proteolytic cleavage, glycosylation and acetylation). Binds also the PDGFR-alpha G-box promoter. May have a role in modulating the cellular response to DNA damage. Implicated in chromatin remodeling. Plays a role in the recruitment of SMARCA4/BRG1 on the c-FOS promoter. Plays an essential role in the regulation of FE65 gene expression.
