Introduction
U6 snRNA-associated Sm-like protein LSm1 (LSM1) has a role in replication-dependent histone mRNA degradation and binds specifically to the 3''-terminal U-tract of U6 snRNA. Sm-like proteins include the Sm sequence motif, which consists of two regions separated by a linker of variable length that folds as a loop. The LSM1 protein facilitates RNA protein interactions and structural modifications which are required during ribosomal subunit assembly. The Sm-like proteins are believed to form a stable heteromer present in tri-snRNP particles, which are vital for pre-mRNA splicing. LSM1 is overexpressed in pancreatic cancer as well as in several breast cancer cell lines.
Description
LSM1 Human Recombinant fused with a 20 amino acid His tag at N-terminus produced in E.Coli is a single, non-glycosylated, polypeptide chain containing 153 amino acids (1-133 a.a.) and having a molecular mass of 17.3kDa. The LSM1 is purified by proprietary chromatographic techniques.
Source
Escherichia Coli.
Physical Appearance
Sterile Filtered colorless solution.
Formulation
The LSM1 solution (1 mg/ml) contains 20mM Tris-HCl buffer (pH 7.5), 1mM DTT, 10% glycerol and 0.1M NaCl.
