Q6ZMZ0

功能描述

E3泛素-protein连接酶,以硫酯的形式接收来自E2泛素结合酶UBE2L3和UBE2L6的泛素,然后直接将泛素转移至靶向底物,例如UCKL1 (PubMed:16709802, PubMed:27485036)。参与自然杀伤细胞和细胞毒性T细胞的细胞溶解活性 (PubMed:10438909)。防止星形孢菌素诱导的细胞死亡 (PubMed:27485036)。 {ECO:0000269|PubMed:10438909, ECO:0000269|PubMed:16709802, ECO:0000269|PubMed:27485036}。

组织特异性

Expressed specifically in natural killer cells, activated macrophages and cytotoxic T-cells (PubMed:10438909). Present in natural killer cells (at protein level) (PubMed:10912506). Ubiquitously expressed with high expression in testis (PubMed:27485036).
