Crystal Structure of the Human SPOP BTB Domain

Function

[SPOP_HUMAN] Inhibits IPF1/PDX1 transactivation of established target promoters, such as insulin, may be by recruiting a repressor complex (By similarity). In complex with CUL3, involved in ubiquitination of BMI1, H2AFY and DAXX, and probably also in ubiquitination and proteasomal degradation of Gli2 or Gli3.[1] [2] [3]

About this Structure

4j8z is a 2 chain structure with sequence from Homo sapiens. Full crystallographic information is available from OCA.
