功能
Possible cell death inducer, in association with other factors. -
疾病相关
Genetic variation in PDCD1 is associated with susceptibility to systemic lupus erythematosus type 2 (SLEB2) [MIM:605218]. Systemic lupus erythematosus is a chronic, inflammatory and often febrile multisystemic disorder of connective tissue. It affects principally the skin, joints, kidneys and serosal membranes. It is thought to represent a failure of the regulatory mechanisms of the autoimmune system. -
序列相似性
Contains 1 Ig-like V-type (immunoglobulin-like) domain. -
发展阶段
Induced at programmed cell death. -
