G蛋白P21 RAC2抗体概述：

B淋巴细胞在抗原的刺激下，能够分化、增殖形成具有针对这种抗原分泌特异性抗体的能力。B细胞的这种能力和量是有限的，不可能持续分化增殖下去，因此产生免疫球蛋白的能力也是极其微小的。将这种B细胞与非分泌型的骨髓瘤细胞融合形成杂交瘤细胞，再进一步克隆化，这种克隆化的杂交瘤细胞是既具有瘤细胞的无限分裂的能力，又具有产生特异性抗体的B淋巴细胞的能力。将这种克隆化的杂交瘤细胞进行培养或注入小鼠腹水内即可获得大量的高效、单一的特异性抗体。这种技术即称为单克隆抗体技术。

产品介绍 RAC2 is a small signaling G protein (more specifically a GTPase), and is a member of the RAC subfamily of the family Rho family of GTPases. RAC proteins play important roles in multiple cellular events, including actin cytoskeletal organization, cell proliferation and survival, cell cycle progression, and gene transcription regulation. RAC1 and RAC2 are also essential components of NADPH oxidase, the enzyme responsible for generating free radicals.

Function : Plasma membrane-associated small GTPase which cycles between active GTP-bound and inactive GDP-bound states. In its active state, binds to a variety of effector proteins to regulate cellular responses such as secretory processes, phagocytosis of apoptotic cells, epithelial cell polarization and growth-factor induced formation of membrane ruffles. Rac1 p21/rho GDI heterodimer is the active component of the cytosolic factor sigma 1, which is involved in stimulation of the NADPH oxidase activity in macrophages (By similarity). Essential for the SPATA13-mediated regulation of cell migration and adhesion assembly and disassembly. Stimulates PKN2 kinase activity.

Isoform B has an accelerated GEF-independent GDP/GTP exchange and an impaired GTP hydrolysis, which is restored partially by GTPase-activating proteins. It is able to bind to the GTPase-binding domain of PAK but not full-length PAK in a GTP-dependent manner, suggesting that the insertion does not completely abolish effector interaction.

Subunit : nteracts (GTP-bound form preferentially) with PKN2 (via the REM repeats); the interaction stimulates autophosphorylation and phosphorylation of PKN2. Interacts with the GEF proteins PREX1, RASGRF2, DOCK1, DOCK2 and DOCK7, which promote the exchange between GDP and GTP, and therefore activate it. Interacts with PARD6A, PARD6B and PARD6G in a GTP-dependent manner. Part of a quaternary complex containing PARD3, some PARD6 protein (PARD6A, PARD6B or PARD6G) and some atypical PKC protein (PRKCI or PRKCZ), which plays a central role in epithelial cell polarization. Found in a trimeric complex composed of DOCK1 and ELMO1, which plays a central role in phagocytosis of apoptotic cells. Interacts with RALBP1 via its effector domain. Interacts with PLXNB1. Probably found in a ternary complex composed of DSCAM, PAK1 and RAC1. Interacts with DSCAM; the interaction requires PAK1. Part of a complex with MAP2K3, MAP3K3, CCM2 and DEF6. Interacts with BAIAP2, BAIAP2L1, CYFIP1/SRA-1 and DEF6. Interacts with Y.pseudotuberculosis YPKA and PLCB2. Interacts with NOXA1. Interacts with ARHGEF2. Interacts with NISCH (By similarity). Interacts with TBC1D2. Interacts with UNKL. Interacts with USP6. Interacts with SPATA13. Interacts with ARHGEF16; mediates activation of RAC1 by EPHA2. Interacts with ITGB4. Interacts with PIP5K1A (By similarity).

Subcellular Location : Cell membrane; Lipid-anchor; Cytoplasmic side. Melanosome.

Tissue Specificity : Isoform B is predominantly identified in skin and epithelial tissues from the intestinal tract. Its expression is elevated in colorectal tumors at various stages of neoplastic progression, as compared to their respective adjacent tissues.

Post-translational modifications : AMPylation at Tyr-32 and Thr-35 are mediated by bacterial enzymes in case of infection by H.somnus and V.parahaemolyticus, respectively. AMPylation occurs in the effector region and leads to inactivation of the GTPase activity by preventing the interaction with downstream effectors, thereby inhibiting actin assembly in infected cells. It is unclear whether some human enzyme mediates AMPylation; FICD has such ability in vitro but additional experiments remain to be done to confirm results in vivo.

GTP-bound active form is ubiquitinated by HACE1, leading to its degradation by the proteasome.

G蛋白P21 RAC2抗体Similarity : Belongs to the small GTPase superfamily. Rho family.
