latent transforming growth factor beta binding protein 4, latent transforming growth factor beta binding protein 4L, Latent-transforming growth factor beta-binding protein 4, LTBP 4, LTBP-4, LTBP4, LTBP4_HUMAN, LTBP4L, LTBP4S.
May be involved in the assembly, secretion and targeting of TGFB1 to sites at which it is stored and/or activated. May play critical roles in controlling and directing the activity of TGFB1. May have a structural role in the extra cellular matrix (ECM).
