Rabbit Anti-GTPBP9/FITC Conjugated antibody
background:
GTP-binding protein 9 is a 396 amino acid protein that belongs to the Obg-related GTPase family under the translation factors (TRAFAC) class. Originally thought to only have GTPase activity, Obg-related GTPase family members have been shown to also have ATPase activity. In Homo sapians, GTPBP9 exhibits a preference for binding ATP over GTP, with GTP binding occuring only at high nucleotide concentration. One cause for ATP affinity and GTP discrimination is thought to be a substitution of glutamine for a hydrophobic amino acid in Obg-related family members; this is the same substitution that inactivates Ras-like GTPases. GTPBP9 contains a SLCterminal TGS domain that binds to ligands and an N-terminal G domain which binds nucleotides. GTPBP9 is expressed as three isoforms produced by alternative splicing.
Function:
Hydrolyzes ATP, and can also hydrolyze GTP with lower efficiency. Has lower affinity for GTP.
Subunit:
Monomer.
Subcellular Location:
Cytoplasm. Nucleus. Nucleus, nucleolus. Note=Predominantly cytoplasmic, shuttles between the nucleus and the cytoplasm.
Tissue Specificity:
Expressed in all tissues tested but its expression is more abundant in testis, liver, lung, and brain. Overexpressed in several malignancies, including cancers of the colon, rectum, ovary, lung, stomach, and uterus.
Similarity:
Belongs to the GTP1/OBG family.
Contains 1 G (guanine nucleotide-binding) domain.
