    Specificity / Sensitivity

    TH1L Antibody recognizes endogenous levels of total TH1L protein.

    Source / Purification

    Polyclonal antibodies are produced by immunizing animals with a synthetic peptide corresponding to residues surrounding Ala132 of human TH1L protein. Antibodies are purified by protein A and peptide affinity chromatography.

    Background

    Negative Elongation Factor (NELF) consists of four subunits: WHSC2 (NELF-A), COBRA-1 (NELF-B), TH1L (NELF-C/D), and NELF-E (1). NELF, together with DRB-sensitivity inducing factor (DSIF), inhibits RNA Polymerase II (RNAPII) elongation resulting in RNAPII promoter proximal pausing, where it awaits additional signaling to resume transcription (2,3). The release of this promoter proximal pausing of RNAPII is a critical regulatory point during transcription and is signaled by phosphorylation of the C-terminal domain (CTD) within the largest subunit of RNAPII and NELF by positive transcription elongation factor (P-TEFb) (4,5). WHSC2 is thought to connect the NELF complex to RNAPII machinery, while NELF-E contains an RNA binding motif that is necessary for NELF function (1,6,7). TH1L, together with COBRA-1, help bring WHSC2 and NELF-E together and are integral subunits of the NELF complex (1).

    In addition to its role in transcription regulation, TH1L is a negative regulator of MAPK signaling by inhibiting A-Raf and PAK1 kinase activities. Research studies have shown that TH1L expression is negatively correlated with breast cancer proliferation and migration (8-10).

    • The Antibody Molecule

      The importance of antibody molecules was first recognized in the 1890s, when it was shown that immunity to tetanus and diphtheria was caused by antibodies against the bacterial exotoxins (1 ). Around the same time, it was shown that antisera

    • Antibody Storage

        General comments: Antibodies, like most proteins, do not like to be freeze-thawed. Avoid repetitive freezing of your solution. The best way to store your antibody is to keep a high protein concentration (>1 mg/ml), add some protease
