Collagen alpha-1(XV) chain is a protein that in humans is encoded by the COL15A1 gene. [5] [6]
This gene encodes the alpha chain of type XV collagen, a member of the FACIT collagen family (fibril-associated collagens with interrupted helices). Type XV collagen has a wide tissue distribution but the strongest expression is localized to basement membrane zones so it may function to adhere basement membranes to underlying connective tissue stroma. Mouse studies have shown that collagen XV deficiency is associated with muscle and microvessel deterioration. [6]
Type XV collagen is known to be a tumor suppressor that can be used to understand tumor cells environment. Type XV collagen provides the membrane with support and cell anchorage but does not typically have a tight structural network. [7]
Changes of collagen XV can be known to lead to cancer-like behavior in tissues. The loss of collagen XV would no longer provide structural support for the membrane, which can cause tumor cells to invade the basement membrane; prompting possible metastasis. The over expression of collagen XV is known to be found in cervical cancer. [8]
For possible future medical purposes the lack of collagen XV present in tissues can be a means for indication of an invasive tumor. [8]
Lysyl oxidase (LOX), also known as protein-lysine 6-oxidase, is an enzyme that, in humans, is encoded by the LOX gene. It catalyzes the conversion of lysine residues into its aldehyde derivative allysine. Allysine form cross-links in extracellular matrix proteins. Inhibition of lysyl oxidase can cause osteolathyrism, but, at the same time, its upregulation by tumor cells may promote metastasis of the existing tumor, causing it to become malignant and cancerous.
Type XVIII collagen is a type of collagen which can be cleaved to form endostatin. The endostatin is from the c terminus end of the collagen XVIII, and is known to have an inhibitory effect on the growth of blood vessels. This is seen with tumors, where endostatin inhibits the growth of the blood vessels of the tumor as well as the overall growth of the tumor.
Collagen alpha-1(V) chain is a protein that in humans is encoded by the COL5A1 gene.
Collagen alpha-5(IV) chain is a protein that in humans is encoded by the COL4A5 gene.
Collagen alpha-1(XVIII) chain is a protein that in humans is encoded by the COL18A1 gene.
Collagen alpha-3(IV) chain is a protein that in humans is encoded by the COL4A3 gene.
Collagen alpha-1(IV) chain (COL4A1) is a protein that in humans is encoded by the COL4A1 gene on chromosome 13. It is ubiquitously expressed in many tissues and cell types. COL4A1 is a subunit of the type IV collagen and plays a role in angiogenesis. Mutations in the gene have been linked to diseases of the brain, muscle, kidney, eye, and cardiovascular system. The COL4A1 gene also contains one of 27 SNPs associated with increased risk of coronary artery disease.
Protein disulfide-isomerase, also known as the beta-subunit of prolyl 4-hydroxylase (P4HB), is an enzyme that in humans encoded by the P4HB gene. The human P4HB gene is localized in chromosome 17q25. Unlike other prolyl 4-hydroxylase family proteins, this protein is multifunctional and acts as an oxidoreductase for disulfide formation, breakage, and isomerization. The activity of P4HB is tightly regulated. Both dimer dissociation and substrate binding are likely to enhance its enzymatic activity during the catalysis process.
Collagen alpha-4(IV) chain is a protein that in humans is encoded by the COL4A4 gene.
Collagen alpha-2(IV) chain is a protein that in humans is encoded by the COL4A2 gene.
Laminin subunit gamma-2 is a protein that in humans is encoded by the LAMC2 gene.
Laminin subunit alpha-3 is a protein that in humans is encoded by the LAMA3 gene.

Collagen alpha-6(IV) chain is a protein that in humans is encoded by the COL4A6 gene.
Collagen alpha-1(XII) chain is a protein that in humans is encoded by the COL12A1 gene.
Prolyl 4-hydroxylase subunit alpha-1 is an enzyme that in humans is encoded by the P4HA1 gene.
Collagen alpha-1(VIII) chain is a protein that in humans is encoded by the COL8A1 gene.
Collagen alpha-1(XIII) chain is a protein that in humans is encoded by the COL13A1 gene.
Prolyl 4-hydroxylase subunit alpha-2 is an enzyme that in humans is encoded by the P4HA2 gene.
Integrin alpha-11 is a protein that, in humans, is encoded by the ITGA11 gene.
