Rabbit Anti-SPA-1/FITC Conjugated antibody
background:
The product of this gene is a mitogen induced GTPase activating protein (GAP). It exhibits a specific GAP activity for Ras-related regulatory proteins Rap1 and Rap2, but not for Ran or other small GTPases. This protein may also hamper mitogen-induced cell cycle progression when abnormally or prematurely expressed. It is localized to the perinuclear region. Two alternatively spliced variants encoding the same isoform have been characterized to date.
Function:
GTPase activator for the nuclear Ras-related regulatory proteins Rap1 and Rap2 in vitro, converting it to the putatively inactive GDP-bound state.
Subcellular Location:
Nucleus. Cytoplasm, perinuclear region. Endomembrane system; Peripheral membrane protein. Note=Mostly localized in the perinuclear membraneous region.
Tissue Specificity:
Expressed in fetal as well as in adult tissues. Expressed abundantly in the lymphoid tissues such as thymus, spleen and peripheral blood lymphocytes and also shows a significant expression in the spinal cord.
Similarity:
Contains 1 PDZ (DHR) domain.
Contains 1 Rap-GAP domain.
