LTBP2 (Latent TGFb Binding Protein 2; also C14orf141) is a 220250kD secreted glycoprotein member of the LTBP family of proteins.
In SDSPAGE and under reducing conditions, LTBP2 runs at 220250kD; under nonreducing conditions, LTBP2 runs between 205220kD.
Although it is described as being a TGFb binding protein, it does not possess the ability to bind covalently to TGFb.
Instead, it appears to bind to heparin sulfate moieties on syndecan4 and perlecan, plus fibrillin1 and fibulin5, suggesting a role in both elastic fiber formation and the maintenance of basement membrane integrity.
In addition, LTPB2 is now known to form a complex with PC5/6A intracellularly, and upon secretion, dampen PC5 activation in the extracellular environment.
Cells known to express LTBP2 include lens and nonpigmented ciliary epithelium, fibroblasts, vascular smooth muscle and chondrocytes.
Mature human LTBP2 is 1786aa in length (aa361821).
It possesses three heparinbinding regions (aa94115, 232249, and 344354), plus 20 EGFlike domains (aa1871818) that contain four interspersed TGFb type binding segments.
Over aa361821, human LTBP2 shares 80%aa sequence identity with mouse LTBP2.
