SMAD3
SMAD3，也被稱為madh3或Smad家族成員3，是一種參與細胞信號傳導的轉錄因子。SMAD3蛋白參與多種過程，如水解酶活性的正向調節、基因表達調節以及跨膜受體蛋白絲氨酸/蘇氨酸激酶信號通路。SMAD3蛋白在多種疾病中發揮重要作用，包括炎癥性腸病、自身免疫性疾病以及腫瘤。在炎癥性腸病中，SMAD3信號通路缺陷會導致腸道炎癥和潰瘍。在自身免疫性疾病中，SMAD3蛋白的激活受損會影響免疫細胞亞型的平衡，導致自身免疫反應。針對SMAD3蛋白的藥物研發主要集中在抑制其活性或阻斷其信號通路。一些小分子抑制劑已被開發用于治療炎癥性腸病和腫瘤。例如，E-SIS3是一種選擇性的SMAD3抑制劑，可以抑制成纖維細胞向肌成纖維細胞分化，從而減輕組織纖維化。此外，一些靶向SMAD3蛋白的抗體藥物也正在臨床研究中，用于治療多種疾病。

Immunoprecipitating SMAD3 in Jurkat whole cell lysate
Lane 1: Rabbit control IgG instead of (1μg) instead of CSB-PA021788ESR2HU in Jurkat whole cell lysate.
For western blotting, a HRP-conjugated anti-rabbit IgG, specific to the non-reduced form of IgG was used as the Secondary antibody (1/50000)
Lane 2: CSB-PA021788ESR2HU (4μg) + Jurkat whole cell lysate (500μg)
Lane 3: Jurkat whole cell lysate (20μg)
IHC image of CSB-PA021788ESR2HU diluted at 1:388 and staining in paraffin-embedded human adrenal gland tissue performed on a Leica BondTM system. After dewaxing and hydration, antigen retrieval was mediated by high pressure in a citrate buffer (pH 6.0). Section was blocked with 10% normal goat serum 30min at RT. Then primary antibody (1% BSA) was incubated at 4°C overnight. The primary is detected by a biotinylated secondary antibody and visualized using an HRP conjugated SP system.
Immunofluorescence staining of A549 cells with CSB-PA021788ESR2HU at 1:129, counter-stained with DAPI. The cells were fixed in 4% formaldehyde, permeabilized using 0.2% Triton X-100 and blocked in 10% normal Goat Serum. The cells were then incubated with the antibody overnight at 4°C. The secondary antibody was Alexa Fluor 488-congugated AffiniPure Goat Anti-Rabbit IgG(H+L).
