BACK (BTB and C-terminal Kelch) domain found in Kelch-like protein 31 (KLHL31)
KLHL31, also termed BTB and kelch domain-containing protein 6, or Kelch repeat and BTB domain-containing protein 1, or Kelch-like protein KLHL, is a transcriptional repressor in MAPK/JNK signaling pathway that regulates cellular functions. Overexpression inhibits the transcriptional activities of both the TPA-response element (TRE) and serum response element (SRE).
