SP1_HUMAN
Interaction Name SP1-MAT2B interaction [1]
Studied Cell Lines Cos-1 and Jurkat human leukemic T cell lines
Ensembl ID
ENSG00000185591
Description Transcription factor Sp1 (SP1) is reported to activate the transcription of MAT2B gene, which leads to an increased expression of the drug-metabolizing enzyme Methionine adenosyltransferase II beta. As a result, the interaction between SP1 and MAT2B can activate the drug-metabolizing process of Methionine adenosyltransferase II beta.

                            hsa-miR-21-3p Liver cancer Suppression
miRBase ID
MIMAT0004494
Interaction Name hsa-miR-21-3p--MAT2B regulation [2]
Studied Cell Lines HepG2 cell line
Description hsa-miR-21-3p is reported to suppress MAT2B mRNA translation by binding to the 3' untranslated region (3'UTR) of MAT2B mRNA, which leads to a decreased expression of the drug-metabolizing enzyme Methionine adenosyltransferase II beta.
