Scientific Data Images for Human Kallikrein 8/Neuropsin Antibody

Kallikrein 8/Neuropsin antibody in Human Brain by Immunohistochemistry (IHC-P).

Kallikrein 8/Neuropsin in Human Brain.

Kallikrein 8/Neuropsin was detected in immersion fixed paraffin-embedded sections of human brain (hippocampus) using Mouse Anti-Human Kallikrein 8/Neuropsin Monoclonal Antibody (Catalog # MAB1719) at 5 µg/mL overnight at 4 °C. Tissue was stained using the Anti-Mouse HRP-DAB Cell & Tissue Staining Kit (brown; Catalog # CTS002) and counterstained with hematoxylin (blue). Specific staining was localized to neuronal cytoplasm.

Background: Kallikrein 8/Neuropsin

Kallikrein 8 (KLK8), also known as neuropsin or ovasin, is a member of the human tissue kallikrein family (1). Two alternatively spliced forms exist, resulting in 260 (isoform 1) and 305 (isoform 2) amino acid (aa) sequences, respectively (2). Isoform 1 consists of a signal peptide (residues 1 to 28), a short pro peptide
(aa 29‑32) and the mature chain (aa 33-260). Isoform 2 is identical to isoform 1, except that a 45 aa segment is inserted in isoform 2 between aa 23 and 24 in isoform 1. Isoform 1 is predominantly expressed in pancreas whereas isoform 2 is preferentially expressed in adult brain and hippocampus, although both forms are expressed in fetal brain and placenta in comparable levels. The brain function of KLK8 seems evident in neuropsin knockout mice that showed abnormalities of synapses and neurons and predisposation to global seizure activity (3, 4). KLK8 is a novel marker for ovarian and cervical cancer carcinomas (5, 6). Recombinant human KLK8, after being activated by lysyl endopeptidase, can cleave fibronectin and several small peptide substrates (7, 8).
