Scientific Data Images for Human LRRC4 Antibody
LRRC4 in Human Brain.
LRRC4 was detected in immersion fixed paraffin-embedded sections of human brain (cerebellum) using 15 µg/mL Sheep Anti-Human LRRC4 Antigen Affinity-purified Polyclonal Antibody (Catalog # AF4995) overnight at 4 °C. Tissue was stained with the Anti-Sheep HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS019) and counterstained with hematoxylin (blue).

Background: LRRC4
LRRC4 (Leu-rich repeat/LRR-containing protein 4; also brain tumor-associated protein) is a 55 kDa (predicted) member of the Leu-rich protein family. It is expressed on neurons and astrocytes, and antagonizes the signaling pathways for cytokines and growth factors. It is reduced in expression in tumors. Human LRRC4 is a type I transmembrane protein that is 653 amino acids (aa) in length. It contains a 489 aa extracellular region (aa 39-527), and a 105 aa cytoplasmic domain. The extracellular region shows nine LRRs (aa 74-288), a C2 type Ig-like domain (aa 354-440), and a Thr rich segment (aa 455-526). Over aa 39-527, human LRRC4 is 98% aa identical to both mouse and canine LRRC4, respectively.
