background

Transforming growth factor beta(2) (TGF-beta(2)), a growth regulator of human lens epithelial cells (HLECs), also regulates the death of these cells. TGF-beta(2)-induced apoptosis in HLECs was preceded by an induction of reactive oxygen species (ROS) and a decrease in glutathione in the intracellular content, indicating that this factor induces oxidative stress in HLECs.

molecular weight

The protein has a predicted MW of 46.6 kDa. Due to glycosylation, the protein migrates to 40-60 kDa&12-13 kDa based on Tris-Bis PAGE result.

available size

100 µg, 500 µg

endotoxin

Less than 1EU per μg by the LAL method.

Function
FUNCTION: [Transforming growth factor beta-2 proprotein]: Precursor of the Latency-associated peptide (LAP) and Transforming growth factor beta-2 (TGF-beta-2) chains, which constitute the regulatory and active subunit of TGF-beta-2, respectively. {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P04202}.; FUNCTION: [Latency-associated peptide]: Required to maintain the Transforming growth factor beta-2 (TGF-beta-2) chain in a latent state during storage in extracellular matrix (By similarity). Associates non-covalently with TGF-beta-2 and regulates its activation via interaction with 'milieu molecules', such as LTBP1 and LRRC32/GARP, that control activation of TGF-beta-2 (By similarity). {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P04202}.; FUNCTION: [Transforming growth factor beta-2]: Multifunctional protein that regulates various processes such as angiogenesis and heart development (PubMed:22772368, PubMed:22772371). Activation into mature form follows different steps: following cleavage of the proprotein in the Golgi apparatus, Latency-associated peptide (LAP) and Transforming growth factor beta-2 (TGF-beta-2) chains remain non-covalently linked rendering TGF-beta-2 inactive during storage in extracellular matrix (By similarity). At the same time, LAP chain interacts with 'milieu molecules', such as LTBP1 and LRRC32/GARP, that control activation of TGF-beta-2 and maintain it in a latent state during storage in extracellular milieus (By similarity). Once activated following release of LAP, TGF-beta-2 acts by binding to TGF-beta receptors (TGFBR1 and TGFBR2), which transduce signal (By similarity). {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P04202, ECO:0000269|PubMed:22772368, ECO:0000269|PubMed:22772371}.
Subellular location
SUBCELLULAR LOCATION: [Latency-associated peptide]: Secreted, extracellular space, extracellular matrix {ECO:0000250|UniProtKB:P01137}.; SUBCELLULAR LOCATION: [Transforming growth factor beta-2]: Secreted {ECO:0000250|UniProtKB:P01137}.
Structure
SUBUNIT: Interacts with the serine proteases, HTRA1 and HTRA3 (By similarity). Interacts with ASPN (PubMed:17827158). Interacts with MFAP5 (By similarity). {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P27090, ECO:0000269|PubMed:17827158}.; SUBUNIT: [Latency-associated peptide]: Interacts with Transforming growth factor beta-2 (TGF-beta-2) chain; interaction is non-covalent and maintains (TGF-beta-2) in a latent state (By similarity). Interacts with LRRC32/GARP; leading to regulate activation of TGF-beta-2 (PubMed:19651619). Interacts with NREP; the interaction results in a decrease in TGFB2 autoinduction (By similarity). {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P27090, ECO:0000269|PubMed:19651619}.; SUBUNIT: [Transforming growth factor beta-2]: Homodimer; disulfide-linked (PubMed:1631557, PubMed:1641027). Interacts with TGF-beta receptors (TGFBR1 and TGFBR2), leading to signal transduction (By similarity). {ECO:0000250|UniProtKB:P01137, ECO:0000250|UniProtKB:P27090, ECO:0000269|PubMed:1631557, ECO:0000269|PubMed:1641027}.
Post-translational modification
PTM: [Transforming growth factor beta-2 proprotein]: The precursor proprotein is cleaved in the Golgi apparatus to form Transforming growth factor beta-2 (TGF-beta-2) and Latency-associated peptide (LAP) chains, which remain non-covalently linked, rendering TGF-beta-2 inactive. {ECO:0000250|UniProtKB:P01137}.
