Five members of the TSP gene family have been identified (Fig. 1). TSP-1 and -2 (Subgroup A) are similar in their domain structure and the fact that they form disulfide-linked trimers. By contrast, TSP-3 and -4, and cartilage oligomeric matrix protein (COMP) (Subgroup B) assemble into pentamers. An...

TSP-1 is released from human blood platelets in response to thrombin treatment and was thus, designated thrombospondin in 1978. Since that time, four other members of the TSP gene family have been discovered. The TSPs are widely expressed in embryonic tissue. However, expression in adult tissue is...
