WebCDC25A is a member of the CDC25 family of dual-specificity phosphatases . Dual-specificity protein phosphatases remove phosphate groups from phosphorylated tyrosine and serine / threonine residues. They represent a subgroup of the tyrosine phosphatase family (as opposed to the serine/threonine phosphatase family). WebCDC25A is a transcriptional target of the E2F–RB1 pathway [11]. The Myc transcription factor initiates CDC25A protein expression and both Myc and CDC25A are expressed at elevated levels in tumors [8, 12,]. Transcription factors, E2F1/2/3 and STAT3, activate the transcription of CDC25s.
