A protein rich in proline and arginine (proline/arginine-rich protein (PARP] has been isolated from dissociative extracts of bovine nasal and articular cartilage, and its primary structure has been determined. The protein has 218 amino acids, giving a calculated protein Mr of 24,075. In nasal cartilage, this protein is in molar concentrations equivalent to(More)
An abundant protein that is identical to the growth-associated protein pleiotrophin (PTN) has been isolated from dissociative extracts of bovine nasal and fetal epiphyseal cartilage. The yield from these tissues was at least 15 micrograms/g wet weight of cartilage. PTN was absent or was present only in trace amounts in mature articular cartilage. An(More)
During the course of characterization of low molecular weight proteins in cartilage, we have isolated a protein from reef shark (Carcharhinus springeri) cartilage that bears a striking resemblance to the tetranectin monomer originally described by Clemmensen et al. (1986, Eur. J. Biochem. 156, 327-333). The protein was isolated by extraction of neural arch(More)
A glycosylated protein (small, cartilage-derived glycoprotein, SCGP) of approximately 18 kDa with unknown function has been isolated from dissociative extracts of bovine nasal cartilage and its primary structure determined. The protein has 121 amino acids, giving a calculated protein molecular weight of 13,878, four disulfide bonds, two N-linked(More)
