Interactions

Transcription initiation protein SPT3 homolog has been shown to interact with GCN5L2,[8][9] TAF6L,[9] TADA3L,[9] TAF5L,[9] SF3B3,[9] SUPT7L,[9] Myc,[10] TAF9,[9] Transformation/transcription domain-associated protein,[9] TAF12,[9] TAF10,[8][9] TAF4[8] and DDB1.[9]

Model organisms

Model organisms have been used in the study of SUPT3H function. A conditional knockout mouse line called Supt3^{tm1a(EUCOMM)Hmgu} was generated at the Wellcome Trust Sanger Institute.[11] Male and female animals underwent a standardized phenotypic screen[12] to determine the effects of deletion.[13][14][15][16] Additional screens performed: - In-depth immunological phenotyping[17]
