  • 功能
    Functions as a cation- and diacylglycerol (DAG)-regulated nucleotide exchange factor activating Ras through the exchange of bound GDP for GTP. May function in mast cells differentiation.
  • 组织特异性
    Expressed by mast cells and their progenitors (at protein level). Specifically expressed in mononuclear leukocytes. Highly expressed in myeloid cells compared to lymphoid cells. Also detected in heart, skeletal muscle, spleen, liver, placenta and lung. Not detected in brain. Isoform 1 is the major isoform in normal individuals. Isoform 2 is more significantly expressed in a patient with asthma. Isoform 3 is more significantly expressed in a patient with asthma and a mastocytosis patient.
  • 序列相似性
    Belongs to the RASGRP family.
    Contains 1 EF-hand domain.
    Contains 1 N-terminal Ras-GEF domain.
    Contains 1 phorbol-ester/DAG-type zinc finger.
    Contains 1 Ras-GEF domain.
  • 发展阶段
    Expressed early during development. Detected in all fetal tissues tested.
  • 结构域
    The phorbol-ester/DAG-type zinc finger mediates the binding and the functional activation by DAG.
  • 细胞定位
    Cytoplasm. Cell membrane. Recruited to membranes upon activation by DAG.
  • Information by UniProt
