The molecular cloning and developmental expression of mouse LTBP-2 are presented here. We established the identity of the cDNA by sequence comparison (80% identity with human LTBP-2) and by chromosome localization (mouse chromosome 12, band D, a region of conserved synteny with the human LTBP-2 gene). In contrast to LTBP-1 and LTBP-3, mouse LTBP-2 apparently is a more modular protein with proline/glycine-rich sequences always alternating with clusters of cysteine-rich structural motifs. We found for the first time that LTBP-2 gene expression in mouse embryos was restricted to cartilage perichondrium and blood vessels, a somewhat surprising result since other LTBP genes are widely expressed in rodent tissues. Therefore, mouse LTBP-2 may play a critical role in the assembly of latent TGF-β complexes in developing elastic tissues such as cartilage and blood vessel.
