Source / Purification

Monoclonal antibody is produced by immunizing animals with a synthetic peptide corresponding to the sequence around Gly338 of human THEX1.

Background

THEX1 (3’hExo) is a 3’ exonuclease that may play a role in the degradation of histone mRNA transcripts (1). A recently identified member of the DEDDh 3' exonuclease family, THEX1 binds the conserved stem-loop structure found at the 3’ end of mRNA in vitro (2). The binding of THEX1 to mRNA requires the presence of a terminal ACCCA sequence and is enhanced by the concurrent binding of stem-loop binding protein (SLBP). Cleavage of histone mRNA by THEX1 exonuclease may help produce the rapid turnover of histone mRNA transcripts associated with the completion of DNA replication (3). Additional evidence suggests that THEX1 may be responsible for excising the remaining few 3’ nucleotides following cleavage by a different enzyme (4).

Species Reactivity

Species reactivity is determined by testing in at least one approved application (e.g., western blot).

Western Blot Buffer

IMPORTANT: For western blots, incubate membrane with diluted primary antibody in 5% w/v BSA, 1X TBS, 0.1% Tween® 20 at 4°C with gentle shaking, overnight.
