资源简介:
Full-length LTK binds to the cytoplasmic tyrosine kinase TNK2 (also known as ACK) indirectly through GRB2 (Pao-Chun et al, 2009). It is possible that this interaction is promoted by one or both of the two NPXY sites in LTK that are believed to recruit GRB2 (Y485, through IRS1 or Y862 through SHC1), but this has not been tested (Ueno et al, 1995; Ueno et al, 1996). In other contexts, TNK2 contributes to cell spreading, metastasis and migration, but its possible role in LTK signaling remains to be clarified (Lougheed et al, 2004; Eisenmann et al, 1999; Modzelewska et al, 2006).
全长型LTK通过GRB2(帕奥-春等,2009年)间接与细胞质酪氨酸激酶TNK2(亦称ACK)结合。有可能这种相互作用是由LTK中的两个NPXY位点之一或两个共同促进的,这两个位点被认为可以招募GRB2(Y485通过IRS1或Y862通过SHC1),但这一假设尚未经过验证(上野等,1995年;上野等,1996年)。在其他情境中,TNK2参与细胞的扩散、转移和迁移,但其可能在LTK信号传导中的作用尚需进一步阐明(洛格希德等,2004年;艾森曼等,1999年;莫德泽尔斯卡等,2006年)。
