靶點詳情

功能：

基因功能參考文獻：
1. A somatic RASA1 mutation in addition to the germline RASA1 mutation, was detected within endothelial cells in capillary malformation-arteriovenous malformation. PMID: 29024832

5. These results and the extreme variable expressivity support the hypothesis that somatic "second hits" are required for the development of vascular anomalies associated with CM-AVM syndrome. In addition, the phenotypes of the affected individuals further clarify that lymphatic manifestations are also part of the phenotypic spectrum of RASA1-related disorders. PMID: 26969842
6. results indicate that, mTOR, Bad, or Survivin are not required for p120 RasGAP fragment N to protect cells from cell death; conclude that downstream targets of Akt other than mTORC1, Bad, or survivin mediate fragment N-induced protection or that several Akt effectors can compensate for each other to induce the pro-survival fragment N-dependent responses PMID: 23826368

8. Low RASA1 expression is associated with Triple-Negative Breast Cancer. PMID: 28108518
