PG-Lb is a small dermatan sulfate proteoglycan that has been previously characterized in chicken. In the developing limb, chick PG-Lb appears to be exclusively expressed in the zone of flattened chondrocytes. We have cloned and sequenced the human homolog to chick PG-Lb from two human chondrocyte cDNA libraries and a human chondrocyte RNA sample. The human homolog has been named DSPG3, as it is the third member of the small dermatan sulfate proteoglycan family to be identified and characterized along with biglycan (PG-I) and decorin (PG-II). DSPG3 maps to chromosome 12q21 and is composed of 1515 nucleotides of cDNA that code for a 322-amino-acid protein. The protein contains three potential glycosaminoglycan attachment sites, two N-glycosylation sites, a poly- glutamic acid stretch, and six cysteines. By Northern analysis, we have demonstrated that DSPG3 is expressed in cartilage, as well as ligament and placental tissues.
The set of physiological processes that allow an embryo or foetus to develop within the body of a female animal. It covers the time from fertilization of a female ovum by a male spermatozoon until birth.

A reference proteome is a set of protein sequences derived from a complete proteome which constitutes a defined standard for a particular user community. Reference proteomes are manually defined according to a number of criteria. They cover the proteomes of well- studied model organisms and other proteomes of interest for biomedical and biotechnological research. Reference proteomes have been selected to provide broad coverage of the tree of life, and constitute a representative cross-section of the taxonomic diversity to be found within UniProtKB.
