Rabbit Polyclonal to Human Protein Tyrosine Phosphatase Alpha ( PTPRA )PTP alpha, a R4 receptor protein tyrosine phosphatase, is implicated in neuron formation, retinal development, cell adhesion, potassium channel regulation, nerve repair, insulin signaling, and cell cycle regulation. PTP alpha activates the Src protein tyrosine kinase during mitosis, resulting in the transition from G2 to mitosis in the cell cycle. PTP alpha is associated with carcinomas of breast, colon, oral squamous cell and prostate. A cytosolic form of PTP alpha, p66 PTP alpha, has recently been isolated. p66 PTP alpha is produced by calpain-mediated proteolytic cleavage and its expression has been detected in nearly all cell types where PTP alpha is expressed. PTP alpha expression has been documented in human neoplastic breast, colon, prostate, and oral tissues, as well as in normal adipose, liver, skeletal muscle, and endothelial cells. ESTs have been isolated from a diverse set of normal and cancerous tissue libraries. |
