TGFBI Human, 182 a.a.

What is TGFBI Human, 182 a.a. and how does it differ from the full-length TGFBI protein?

TGFBI Human, 182 a.a. is a recombinant protein fragment containing amino acids 502-683 of the full-length human TGFBI (Transforming growth factor-beta-induced protein ig-h3). While the complete TGFBI protein consists of 683 amino acids with multiple functional domains, this 182 a.a. fragment represents the C-terminal portion with a molecular mass of approximately 19.9 kDa . This recombinant version is produced in E. coli as a single, non-glycosylated polypeptide, which differs from the naturally occurring full-length TGFBI that undergoes post-translational modifications in mammalian cells . The 182 a.a. fragment is particularly useful for studying specific C-terminal interactions without interference from other domains present in the complete protein.

What are the key structural domains and functional motifs present in the TGFBI Human, 182 a.a. fragment?

The 182 a.a. fragment of TGFBI (amino acids 502-683) contains significant functional domains including part of the fourth FAS1 domain and the C-terminal region. Based on sequence analysis and functional studies, this fragment likely contains:

• Portions of the fourth fasciclin-like domain which mediates interactions with integrins, particularly α3β1, αVβ3 and αVβ5

• The C-terminal region which may contain the RGD motif that facilitates binding to various integrins

• Structural elements that contribute to extracellular matrix interactions

The amino acid sequence provided (MGTVMDVLKG DNRFSMLVAA IQSAGLTETL NREGVYTVFA PTNEAFRALP PRERSRLLGD AKELANILKY HIGDEILVSG GIGALVRLKS LQGDKLEVSL KNN) represents part of this fragment and contains regions that contribute to TGFBI's ability to interact with cellular components and the extracellular matrix .

What are the optimal storage and handling conditions for maintaining the stability of TGFBI Human, 182 a.a. in research applications?

For optimal stability of TGFBI Human, 182 a.a., researchers should implement the following evidence-based protocols:
