  • FunctionProtease that regulate the availability of nsulin-like growth factors (IGFs) by cleaving IGF-binding proteins. Represses signaling by TGF-beta family members.
  • Tissue specificityExpressed in a variety of tissues, with strongest expression in placenta.
  • Involvement in diseaseVariations in the promoter region of HTRA1 are the cause of susceptibility to age-related macular degeneration type 7 (ARMD7) [MIM:610149]. ARMD is the leading cause of vision loss and blindness among older individuals in the developed word. It is classified as either dry (nonneovascular) or wet (neovascular). ARMD7 is a wet form, in which new blood vessels form and break beneath the retina. This leakage causes permanent damage to surrounding retinal tissue, distorting and destroying central vision. Wet ARMD is more prevalent among Asians than Caucasians.
    Defects in HTRA1 are the cause of cerebral autosomal recessive arteriopathy with subcortical infarcts and leukoencephalopathy (CARASIL) [MIM:600142]. CARASIL is characterized by nonhypertensive cerebral small-vessel arteriopathy with subcortical infarcts, alopecia, and spondylosis, with an onset in early adulthood. On neuropathological examination, arteriosclerosis associated with intimal thickening and dense collagen fibers, loss of vascular smooth-muscle cells, and hyaline degeneration of the tunica media has been observed in cerebral small arteries.

    Contains 1 IGFBP N-terminal domain.

  • Anti-htrA1 antibody (ab38610) at 1/1000 dilution + Human placenta tissue lysate at 35 µg/ml

    Peroxidase-conjugated goat anti-rabbit IgG (H+L) at 1/5000 dilution

    Predicted band size : 51 kDa
    Observed band size : 51 kDa

    Incubation time was overnight at 4°C. Blocking/Dilution buffer: 5% NFDM/TBST.

  • Immunohistochemistry (Formalin/PFA-fixed paraffin-embedded sections) analysis of human breast carcinoma tissue labelling htrA1 with ab38610. Tissue was fixed with formaldehyde and blocked with 3% BSA for 0.5 hour at 38°C; antigen retrieval was by heat mediation with a citrate buffer (pH6). Samples were incubated with primary antibody (1/25) for 1 hour at 37°C. A peroxidase-conjugated goat anti-rabbit polyclonal (ready to use) was used as the secondary antibody.
