特異性This polyclonal antibody reacts with NTAL, a 30 kDa transmembrane adaptor protein expressed in membrane microdomains (rafts) of B cells, NK cells and myeloid cells. We have data to indicate that this antibody may not cross react with Mouse. However, this has not been conclusively tested and expression levels may vary in certain cell lines/tissues.
The application notes include recommended starting dilutions; optimal dilutions/concentrations should be determined by the end user.
追加情報WB: Use at a concentration of 1 µg/ml (incubation 60 min at RT; or overnight at 4°C). Sample preparation: Lysis buffer with 1% laurylmaltoside. Use under non reducing conditions. Detects a band of approximately 30 kDa.
Not yet tested in other applications.

機能Involved in FCER1 (high affinity immunoglobulin epsilon receptor)-mediated signaling in mast cells. May also be involved in BCR (B-cell antigen receptor)-mediated signaling in B-cells and FCGR1 (high affinity immunoglobulin gamma Fc receptor I)-mediated signaling in myeloid cells. Couples activation of these receptors and their associated kinases with distal intracellular events through the recruitment of GRB2.
組織特異性Highly expressed in spleen, peripheral blood lymphocytes, and germinal centers of lymph nodes. Also expressed in placenta, lung, pancreas and small intestine. Present in B-cells, NK cells and monocytes. Absent from T-cells (at protein level).
関連疾患Note=LAT2 is located in the Williams-Beuren syndrome (WBS) critical region. WBS results from a hemizygous deletion of several genes on chromosome 7q11.23, thought to arise as a consequence of unequal crossing over between highly homologous low-copy repeat sequences flanking the deleted region. Haploinsufficiency of LAT2 may be the cause of certain cardiovascular and musculo-skeletal abnormalities observed in the disease.
翻訳後修飾Phosphorylated on tyrosines following cross-linking of BCR in B-cells, FCGR1 in myeloid cells, or FCER1 in mast cells; which induces the recruitment of GRB2. May be polyubiquitinated.
