Gene Information

human ... SMAD4(4089)

General description

The gene SMAD4 (mothers against decapentaplegic homolog 4), also known as DPC4 (deleted in pancreatic carcinoma), is mapped to human chromosome 18q21.1. The protein localizes in the cytoplasm and nucleus.

Immunogen

SMAD4 (NP_005350, 56 a.a. ~ 165 a.a) partial recombinant protein with GST tag. MW of the GST tag alone is 26 KDa.

Biochem/physiol Actions

Upon TGFβ (transforming growth factor β) activation, SMAD (mothers against decapentaplegic homolog) proteins are responsible for transcription activation in the nucleus. SMAD4 is a crucial protein of TGFβ signaling. It promotes association of SMAD2/4 to DNA and helps SMAD1/2 in transcription stimulation. Mutations in SMAD4 are linked with juvenile polyposis syndrome, hereditary haemorrhagic telangiectasia and Myhre syndrome. In renal cell carcinoma, it activates forkhead box protein H1 and thereby inhibits the progression of the carcinoma. SMAD4 is considered as a tumor suppressor protein.
