This protein was originally described as an endothelial cell-specific mitogen. VEGF plays a role in normal physiological functions such as haematopoiesis, bone formation, and wound healing.

This study aimed to perform molecular characterization of the human VEGF promoter region. The sequence of the promoter region of the human VEGF (Accession no. AF095785) was obtained from Gene bank. The open reading frames (ORFs), restrictions/methylation sites against a total of 560 recognition sequences, a total of three TATA boxes (TATA, tata, Goldberg Hogness Sequences) were identified using clustal X feature of VectorNTI. Transcriptional factors binding sites (TFBS) were identified using online tool. Promoter prediction was determined by doing manually matching of TFBS with TATA box from outward in.
