  • 产品描述：

    The DNA sequence coding for the LOXL2 monoclonal antibody produced from the animals with recombinant human LOXL2 immunization was cloned into the expression vector, which was further transfected into a cell line for in vitro expression. The product is the recombinant LOXL2 monoclonal antibody. It specifically recognizes and detects the LOXL2 from human, mouse, and rat samples. It belongs to the rabbit IgG. The affinity-chromatography purification method was used to purify this LOXL2 antibody. This LOXL2 antibody has been validated for use in ELISA, WB, IHC, IF, and FC analyses.

    Similar to LOX, LOXL2 promotes the cross-linking of collagen and elastin in the extracellular matrix (ECM). LOXL2 is also involved in the regulation of signaling pathways inside or outside the cell. Disorders of LOXL2 lead to diverse diseases, such as fibrosis, heart disease, and cancer. The expression and function of LOXL2 in tumor progression vary among tissue types. Over-expression of LOXL2 promotes tumor metastasis.

  • 功能：
    Mediates the post-translational oxidative deamination of lysine residues on target proteins leading to the formation of deaminated lysine (allysine). Acts as a transcription corepressor and specifically mediates deamination of trimethylated 'Lys-4' of histone H3 (H3K4me3), a specific tag for epigenetic transcriptional activation. Shows no activity against histone H3 when it is trimethylated on 'Lys-9' (H3K9me3) or 'Lys-27' (H3K27me3) or when 'Lys-4' is monomethylated (H3K4me1) or dimethylated (H3K4me2). Also mediates deamination of methylated TAF10, a member of the transcription factor IID (TFIID) complex, which induces release of TAF10 from promoters, leading to inhibition of TFIID-dependent transcription. LOXL2-mediated deamination of TAF10 results in transcriptional repression of genes required for embryonic stem cell pluripotency including POU5F1/OCT4, NANOG, KLF4 and SOX2. Involved in epithelial to mesenchymal transition (EMT) via interaction with SNAI1 and participates in repression of E-cadherin CDH1, probably by mediating deamination of histone H3. During EMT, involved with SNAI1 in negatively regulating pericentromeric heterochromatin transcription. SNAI1 recruits LOXL2 to pericentromeric regions to oxidize histone H3 and repress transcription which leads to release of heterochromatin component CBX5/HP1A, enabling chromatin reorganization and acquisition of mesenchymal traits. Interacts with the endoplasmic reticulum protein HSPA5 which activates the IRE1-XBP1 pathway of the unfolded protein response, leading to expression of several transcription factors involved in EMT and subsequent EMT induction. Involved in E-cadherin repression following hypoxia, a hallmark of EMT believed to amplify tumor aggressiveness, suggesting that it may play a role in tumor progression. When secreted into the extracellular matrix, promotes cross-linking of extracellular matrix proteins by mediating oxidative deamination of peptidyl lysine residues in precursors to fibrous collagen and elastin. Acts as a regulator of sprouting angiogenesis, probably via collagen IV scaffolding. Acts as a regulator of chondrocyte differentiation, probably by regulating expression of factors that control chondrocyte differentiation.
