Dim2 / TXNL4B Protein Description

Dim2, also known as TXNL4B thioredoxin-like 4B,N-Histidine-tagged) is a member of the DIM1 family which has a vital role in pro-mRNA splicing. The Dim protein family is composed of two classes, Dim1and Dim2, which share a common thioredoxin-like fold. In spite of their biological and structural similarities, Dim1 and Dim2 proteins differ in many aspects. Dim1 bears distinctive structural motifs responsible for its interaction with other spliceosome components. Dim2 forms homodimers and contains specific domains required for its interactions with partners. This originality suggests that although both proteins are involved in pre-mRNA splicing, they are likely to be involved in different biological pathways. Dim2 produced in E.Coli is a single, non-glycosylated polypeptide chain containing 185 amino acids (1-149 a.a) and having a molecular mass of 21.1kDa. It is fused to a 36 amino acid His-tag at N-terminus & purified by proprietary chromatographic techniques. Dim2 is required in cell cycle progression for S/G2 transition and has been shown to interact with PRPF6.
