研究背景

機能:

Type I collagen is a member of group I collagen (fibrillar forming collagen).

PTMs:

Prolines at the third position of the tripeptide repeating unit (G-X-Y) are hydroxylated in some or all of the chains.

細胞の位置付け:

Secreted>Extracellular space>Extracellular matrix.

Extracellular region or secreted Cytosol Plasma membrane Cytoskeleton Lysosome Endosome Peroxisome ER Golgi apparatus Nucleus Mitochondrion Manual annotation Automatic computational assertionSubcellular location
組織特異性:

Forms the fibrils of tendon, ligaments and bones. In bones the fibrils are mineralized with calcium hydroxyapatite.

タンパク質ファミリー:

The C-terminal propeptide, also known as COLFI domain, have crucial roles in tissue growth and repair by controlling both the intracellular assembly of procollagen molecules and the extracellular assembly of collagen fibrils. It binds a calcium ion which is essential for its function.

Belongs to the fibrillar collagen family.

Application: WB    Species: human    Sample: LF cells

Fig. 3. Fibrosis phenotype and THBS1/TGFβ1 expression were significantly elevated in the LFH group. (A) The thickness of LF was measured by MRI before operation. The thickness of LF at the L4/5 facet joint level was indicated by red arrow. (B) Representative tissues of LF acquired from patients with spinal surgery. The top three were from non-LFH patients and the bottom three were from LFH patients. Scale bar = 5 mm. (C) Representative images of H&E, MASSON, and EVG staining of the non-LFH group (n = 6) and the LFH group (n = 6). The yellow dotted area represents collagen fibers. Scale bar = 20 μm. (D) Immunohistochemical staining of THBS1, TGFβ1, COL1A2, and α-SMA in the LF samples from LFH group (n = 6) and non-LFH group (n = 6), and the percentage of positive cells was quantified. Scale bar = 20 μm. (E) TEM of LF ultrastructure of non-LFH and LFH groups. The yellow area represents elastin fibers. Scale bar = 8 μm. (F) The qRT-PCR analysis results showing that LFH group (n = 6) had a higher mRNA level of THBS1, TGFβ1, ACTA2 (α-SMA), and COL1A2 compared with non-LFH group (n = 6). The 2−ΔΔCt method was used to normalized with GAPDH. (G) Western blotting assay of THBS1, TGFβ1, COL1A2, and α-SMA protein levels of LF samples of the two groups. GAPDH served as the loading control.
