File Protein ACAN PDB 1tdq.png thumb Structure of the protein core of aggrecan or chondroitin sulfate proteoglycan 1 Chondroitin sulfate proteoglycans CSPGs are proteoglycans consisting of a protein core and a chondroitin sulfate side chain. They are known to be structural components of a variety of human tissues, including cartilage , and also play key roles in neural development and glial scar formation. They are known to be involved in certain cell processes, such as cell adhesion , cell growth, receptor binding, cell migration, and interaction with other extracellular matrix constituents. ref name Rhodes cite pmid 14690476 ref They are also known to interact with laminin , fibronectin , tenascin , and collagen . ref name Rhodes CSPGs are generally secreted from cells. Importantly, CSPGs are known to inhibit axon regeneration after spinal cord injury. CSPGs contribute to glial scar formation post injury, acting as a barrier against new axons growing into the injury site. ref name Justin cite pmid 21848846 ref CSPGs play a crucial role in why spinal cord injuries are so debilitating and often incurable. General structure Chondroitin sulfate proteoglycans are composed of a core protein and a sugar side chain. The core protein is generally a glycoprotein , and the side chains are glycosaminoglycan GAG sugar chains attached through a covalent bond . ref name Rhodes The GAG side chains are of different lengths depending on the CSPG. Each GAG chain consists of a linear pattern of alternating monosaccharide units uronic acid and either N acetylglucosamine or N acetylgalactosamine . ref name Rhodes Types of CSPGs The following CSPGs have been identified Aggrecan CSPG1 Versican CSPG2 Neurocan CSPG3 CSPG4 melanoma associated chondroitin sulfate proteoglycan, NG2 CSPG5 SMC3 CSPG6, structural maintenance of chromosomes 3 Brevican CSPG7 CD44 CSPG8, cluster of differentiation 44 Phosphacan Neurocan, brevican, versican, and aggrecan all share similar N terminal and C terminal d ... more details

Infobox Disease Name Sclerocornea Image Caption DiseasesDB ICD10 ICD9 ICDO OMIM 269400 OMIM mult OMIM2 181700 MedlinePlus eMedicineSubj eMedicineTopic MeshID Sclerocornea is a congenital anomaly of the human eye eye in which the cornea blends with sclera , having no Corneal limbus clear cut boundary . The extent of the resulting opacity varies from peripheral to total sclerocornea totalis . The severe form is thought to be inherited in an autosomal recessive manner, but there may be another, milder form that is expressed in a dominant fashion. In some cases the patients also have abnormalities beyond the eye Systemic disease systemic , such as limb deformities and craniofacial and genitourinary defects. According to one tissue analysis performed after corneal transplantation , the sulfation pattern of keratan sulfate proteoglycan s in the affected area is typical for corneal rather than scleral tissue. ref name pmid16488970 cite journal author Young RD, Quantock AJ, Sotozono C, Koizumi N, Kinoshita S title Sulphation patterns of keratan sulphate proteoglycan in sclerocornea resemble cornea rather than sclera journal Br J Ophthalmol volume 90 issue 3 pages 391 3 year 2006 month March pmid 16488970 pmc 1856931 doi 10.1136 bjo.2005.085803 url http bjo.bmj.com cgi pmidlookup?view long&pmid 16488970 ref Sclerocornea may be concurrent with cornea plana .
