  • 一次抗体 備考

    GTPase Activating Protein (GAP) is capable of stimulating the hydrolysis of GTP by ras p21 proteins, though GAP has little effect on the oncogenic forms of ras. It is also known that several tyrosine kinases such as platelet derived growth factor receptor and epidermal growth factor receptor are involved in the tyrosine phosphorylation of GAP. It has therefore been suggested that GAP may provide a connection or link between growth factor receptors and the ras p21 family.

ICC/IF
Use a concentration of 5 µg/ml.

Immunofluorescence staining of GAP in mouse fibroblast cells results in diffuse cytoplasmic staining. Following the addition of PDGF, immunofluorescence staining shows that some GAP rapidly translocates to the plasma membrane.
WB
Use a concentration of 10 µg/ml.

By Western blot, this antibody recognizes a single 120 kDa protein representing ras GAP from RS-2 cell lysate.

ターゲット情報

  • 機能

    Inhibitory regulator of the Ras-cyclic AMP pathway. Stimulates the GTPase of normal but not oncogenic Ras p21.

  • 組織特異性

    In placental villi, detected only in the trophoblast layer (cytotrophoblast and syncytiotrophoblast). Not detected in stromal, endothelial or Hofbauer cells (at protein level).

  • 関連疾患

    Note=Mutations in the SH2 domain of RASA seem to be oncogenic and cause basal cell carcinomas.
    Defects in RASA1 are the cause of capillary malformation-arteriovenous malformation (CMAVM) [MIM:608354]. CMAVM is a disorder characterized by atypical capillary malformations that are multiple, small, round to oval in shape and pinkish red in color. These capillary malformations are associated with either arteriovenous malformation, arteriovenous fistula, or Parkes Weber syndrome.
    Defects in RASA1 are a cause of Parkes Weber syndrome (PKWS) [MIM:608355]. PKWS is a disorder characterized by a cutaneous flush with underlying multiple micro-arteriovenous fistulas, in association with soft tissue and skeletal hypertrophy of the affected limb.
