Disease

[TGFB2_HUMAN] Note=A chromosomal aberration involving TGFB2 is found in a family with Peters anomaly. Translocation t(1;7)(q41;p21) with HDAC9. Defects in TGFB2 are the cause of Loeys-Dietz syndrome 4 (LDS4) [MIM:614816]. An aortic aneurysm syndrome with widespread systemic involvement. LDS4 is characterized by arterial tortuosity, aortic dissection, intracranial aneurysm and subarachnoid hemorrhage, hypertelorism, bifid uvula, pectus deformity, bicuspid aortic valve, arachnodactyly, scoliosis, foot deformities, dural ectasia, joint hyperflexibility, and thin skin with easy bruising and striae.^[1]

Function

[TGFB2_HUMAN] TGF-beta 2 has suppressive effects on interleukin-2 dependent T-cell growth.

Publication Abstract from PubMed

The transforming growth factors-beta (TGF-beta 1 through -beta 5) are a family of homodimeric cytokines that regulate proliferation and function in many cell types. Family members have 66 to 80% sequence identity and nine strictly conserved cysteines. A crystal structure of a member of this family, TGF-beta 2, has been determined at 2.1 angstrom (A) resolution and refined to an R factor of 0.172. The monomer lacks a well-defined hydrophobic core and displays an unusual elongated nonglobular fold with dimensions of approximately 60 A by 20 A by 15 A. Eight cysteines form four intrachain disulfide bonds, which are clustered in a core region forming a network complementary to the network of hydrogen bonds. The dimer is stabilized by the ninth cysteine, which forms an interchain disulfide bond, and by two identical hydrophobic interfaces. Sequence profile analysis of other members of the TGF-beta superfamily, including the activins, inhibins, and several developmental factors, imply that they also adopt the TGF-beta fold.
