Disease
[SART3_HUMAN] Defects in SART3 are the cause of disseminated superficial actinic porokeratosis type 1 (DSAP1) [MIM:175900]. DSAP1 is an autosomal dominant disorder, characterized by multiple superficial keratotic lesions surrounded by a slightly raised keratotic border, developing during the third or fourth decade of life on sun-exposed areas of skin.[1]
Function
[SART3_HUMAN] Regulates Tat transactivation activity through direct interaction. May be a cellular factor for HIV-1 gene expression and viral replication.[2]
