Tīmeklis来自胰腺癌细胞的外泌体通常富含跨膜蛋白，用于支持肿瘤微环境的重编程和远处转移性病变的进展。 我们的研究发现，由外泌体传递的跨膜糖蛋白CD44通过重编程肿瘤微环境，参与了胰腺癌的转移过程。 CD44与整合素α6β4相互作用形成复合物，激活细胞内骨架蛋白及其信号通路，进而调控Src和Ras信号级联反应，促进肿瘤细胞的运动。 值得 … Tīmeklis2024. gada 25. marts · In addition, images also showed that LAMP2B colocalization with LAMP2A is lower than expected (73.88 ± 13.09%), indicating that both LAMP2 isoforms are often segregated into different vesicles (fig. S6C). Overall, our evidence indicates that LAMP2A, but not LAMP2B, participates in the loading of proteins containing …

Tīmeklis2024. gada 15. okt. · LAMP2B retains the lysosomal targeting signal, gly-tyr-x-x, and has the same number of potential glycosylation sites as LAMB2A. The LAMP2B … Lysosome-associated membrane protein 2 (LAMP2), also known as CD107b (Cluster of Differentiation 107b) and Mac-3, is a human gene. Its protein, LAMP2, is one of the lysosome-associated membrane glycoproteins. The protein encoded by this gene is a member of a family of membrane glycoproteins. This … Skatīt vairāk The gene for LAMP2 has 9 coding exons and 2 alternate last exons, 9a and 9b.
