产品介绍 : Rab17 belongs to the Rab family of small Ras-like GTPases. It is specifically expressed in epithelial cells and is upregulated during cell polarization. Immunofluorescence staining studies indicate that Rab17 is associated with the perinuclear recycling endosome in nonpolarized epithelial cells and with the apical recycling endosome in polarized epithelial cells. The function of Rab17 remains unclear. Reports of Rab17 colocalization with internalized IgA in the apical endosome suggest that it may regulate receptor-mediated transcytosis. Rab17 has also been shown to regulate melanocytic filopodia formation and melanosome trafficking. siRNA knockdown of Rab17 in melanoma cells induces melanosome accumulation in the cell periphery.
Function:
The small GTPases Rab are key regulators of intracellular membrane trafficking, from the formation of transport vesicles to their fusion with membranes. Rabs cycle between an inactive GDP-bound form and an active GTP-bound form that is able to recruit to membranes different set of downstream effectors directly responsible for vesicle formation, movement, tethering and fusion. That Rab is involved in transcytosis, the directed movement of endocytosed material through the cell and its exocytosis from the plasma membrane at the opposite side. Mainly observed in epithelial cells, transcytosis mediates for instance, the transcellular transport of immunoglobulins from the basolateral surface to the apical surface. Most probably controls membrane trafficking through apical recycling endosomes in a post-endocytic step of transcytosis. Required for melanosome transport and release from melanocytes, it also regulates dendrite and dendritic spine development (By similarity). May also play a role in cell migration.
Subcellular Location:
Recycling endosome membrane; Lipid-anchor; Cytoplasmic side (By similarity). Cell projection, dendrite (By similarity). Note=May also localize at the basolateral and apical plasma membrane. In neurons, localizes to the cell body and dendritic shaft and spine (By similarity).
Tissue Specificity:
Expressed in melanocytes (at protein level).
Similarity:
Belongs to the small GTPase superfamily. Rab family.

文献和实验PNAS：RAS 抑制剂又添一员，新型蛋白模拟物或为癌症治疗
导读RAS 是肿瘤患者中最常见的致癌基因之一，目前包括 KRAS、NRAS 以及 HRAS 三种亚型。其中，NRAS 突变多见于黑色素瘤和急性髓系白血病，HRAS 突变多见于膀胱癌和头颈癌，而 KRAS 突变比其他两种更常见，最常发生在肺癌、胰腺癌以及结直肠癌。由于在癌症中的 Ras 蛋白经常发生突变，因此 Ras 突变成为了科学家们着力攻克的热点。RAS 曾被医学界称为「不可成药靶点」，科学家们在研究有效的 RAS 抑制剂方面已经摸索尝试了 30 余年，直至近几年才获得了重大进展。当前已经
Ras 信号通路 很多生长因子如EGF、PDGF、FGF等激活受体酪氨酸激酶后，通过中介分子可活化由原癌基因FaS编码的Ras蛋白 ，后者能进一步催化其底物蛋白的酪氨酸磷酸化反应，并引发蛋白磷酸化的级联反应，最终导致细胞的增殖效应。由于Ras蛋白为多种生长因子信号转导过程所共有，故把此信号转导途径称为Ras通路。 Ras蛋白是癌基因las的编码产物，人类有3种ras基因，即H―FaS、K―las和N―Fas，分布于不同染色体上，能编码蛋白质P21。所有的Ras―P21均有结合鸟
