Description

Lysyl oxidase-like 2 (LOXL2) plays a central role in extracellular matrix remodeling through its enzymatic crosslinking of collagen and elastin fibers. Beyond its structural functions, LOXL2 has emerged as a significant player in cancer biology, where it promotes epithelial-to-mesenchymal transition, tumor invasion, and metastatic progression. Its involvement in signal transduction pathways makes it a compelling target for researchers investigating tumor microenvironment dynamics and fibrotic disease mechanisms.

This recombinant monoclonal antibody, clone 2E5, offers the reproducibility and batch consistency that demanding experimental workflows require. Produced using recombinant technology with a defined sequence, it eliminates the lot-to-lot variability that can compromise longitudinal studies or multi-site collaborations. The rabbit IgG format provides strong signal amplification across detection platforms.

Validated across multiple applications, this antibody demonstrates versatility for diverse experimental approaches. Western blot analysis confirms detection in human cancer cell lines including MCF-7 and PC3, with cross-species reactivity demonstrated in mouse and rat brain tissue. The observed band at approximately 53 kDa differs from the predicted 87 kDa molecular weight, likely reflecting detection of a processed or cleaved form of LOXL2, which undergoes proteolytic maturation during secretion. Immunohistochemistry validation in human prostate and placenta tissues shows clear staining patterns using standard citrate buffer antigen retrieval protocols. Immunofluorescence studies in HepG2 cells and flow cytometry analysis in A549 cells further expand its utility for subcellular localization and quantitative single-cell studies.

For researchers exploring LOXL2's contributions to cancer progression, metastasis, or fibrotic remodeling, this antibody provides a reliable tool across protein expression, tissue localization, and cell-based analytical platforms.

Target Background

Function

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.
