HNRNPH1 Protein, Human (His-SUMO)

Cat. No.: HY-P72233
COA Handling Instructions

The HNRNPH1 protein is an important component of the hnRNP complex and plays a key role in pre-mRNA processing events leading to mRNA conversion in the cytoplasm. Functionally, it cooperates with CUGBP1 to regulate alternative splicing of pre-mRNA, specifically inhibiting the inclusion of insulin receptor (IR) pre-mRNA exon 11 in myoblasts. HNRNPH1 Protein, Human (His-SUMO) is the recombinant human-derived HNRNPH1 protein, expressed by E. coli , with N-6*His, N-SUMO labeled tag. The total length of HNRNPH1 Protein, Human (His-SUMO) is 448 a.a., with molecular weight of ~65.1 kDa.

Background

The HNRNPH1 protein plays a crucial role as a component of heterogeneous nuclear ribonucleoprotein (hnRNP) complexes, pivotal entities in the processing events that precede the functional transformation of pre-mRNAs into translatable mRNAs in the cytoplasm. Functionally, HNRNPH1 mediates the regulation of pre-mRNA alternative splicing, with notable inhibitory effects on insulin receptor (IR) pre-mRNA exon 11 inclusion in myoblasts, a process it accomplishes in collaboration with CUGBP1. HNRNPH1 demonstrates a specific binding affinity for IR RNA and poly(RG), and it forms part of a ternary complex alongside FUBP2, PTBP1, and PTBP2. Additionally, HNRNPH1 is identified in the spliceosome C complex and interacts with IGF2BP1, CUGBP1 (in an RNA-dependent manner), and MBNL1 (in an RNA-independent manner). These interactions underscore the multifaceted and dynamic role of HNRNPH1 in orchestrating pre-mRNA processing and alternative splicing, contributing to the intricate regulation of gene expression.

Help & FAQs
  • Do most proteins show cross-species activity?

    Species cross-reactivity must be investigated individually for each product. Many human cytokines will produce a nice response in mouse cell lines, and many mouse proteins will show activity on human cells. Other proteins may have a lower specific activity when used in the opposite species.

The reconstitution calculator equation

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration

Volume (to add to vial) = Mass (in vial) ÷ Desired Reconstitution Concentration
= ÷

The dilution calculator equation

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)

This equation is commonly abbreviated as: C1V1 = C2V2

Concentration (start) × Volume (start) = Concentration (final) × Volume (final)
× = ×

The specific activity calculator equation

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)

Specific Activity (Unit/mg) = 106 ÷ Biological Activity (ED50)
Unit/mg = 106 ÷ ng/mL
