Summaries for LTBP1 Gene

Entrez Gene Summary for LTBP1 Gene

  • The protein encoded by this gene belongs to the family of latent TGF-beta binding proteins (LTBPs). The secretion and activation of TGF-betas is regulated by their association with latency-associated proteins and with latent TGF-beta binding proteins. The product of this gene targets latent complexes of transforming growth factor beta to the extracellular matrix, where the latent cytokine is subsequently activated by several different mechanisms. Alternatively spliced transcript variants encoding different isoforms have been identified. [provided by RefSeq, Jul 2008]

GeneCards Summary for LTBP1 Gene

LTBP1 (Latent Transforming Growth Factor Beta Binding Protein 1) is a Protein Coding gene. Diseases associated with LTBP1 include Geleophysic Dysplasia and Bone Fracture. Among its related pathways are ERK Signaling and Akt Signaling. Gene Ontology (GO) annotations related to this gene include calcium ion binding and transforming growth factor beta binding. An important paralog of this gene is LTBP2.

UniProtKB/Swiss-Prot for LTBP1 Gene

  • 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 extracellular matrix (ECM).

    • The large latent complex of TGFB1 from platelets is composed of the TGFB1 molecule non-covalently associated with a disulfide-bonded complex of a dimer of the N-terminal propeptide of the TGFB1 precursor and LTBP1. LTBP1 does not bind directly to active TGFB1 (PubMed:10930463). Interacts with FBN2 (PubMed:12429738). Interacts with ADAMTSL2 (PubMed:18677313). Interacts (via C-terminal domain) with FBN1 (via N-terminal domain) (PubMed:17293099, PubMed:12429738).
