Function
Ligand for multiple Notch receptors and involved in the mediation of Notch signaling. May be involved in cell-fate decisions during hematopoiesis. Seems to be involved in early and late stages of mammalian cardiovascular development. Inhibits myoblast differentiation (By similarity). Enhances fibroblast growth factor-induced angiogenesis (in vitro). -
Tissue specificity
Widely expressed in adult and fetal tissues. In cervix epithelium expressed in undifferentiated subcolumnar reserve cells and squamous metaplasia. Expression is up-regulated in cervical squamous cell carcinoma. Expressed in bone marrow cell line HS-27a which supports the long-term maintenance of immature progenitor cells. -
Involvement in disease
Defects in JAG1 are the cause of Alagille syndrome type 1 (ALGS1) [MIM:118450]. Alagille syndrome is an autosomal dominant multisystem disorder defined clinically by hepatic bile duct paucity and cholestasis in association with cardiac, skeletal, and ophthalmologic manifestations. There are characteristic facial features and less frequent clinical involvement of the renal and vascular systems.
Defects in JAG1 are a cause of tetralogy of Fallot (TOF) [MIM:187500]. TOF is a congenital heart anomaly which consists of pulmonary stenosis, ventricular septal defect, dextroposition of the aorta (aorta is on the right side instead of the left) and hypertrophy of the right ventricle. This condition results in a blue baby at birth due to inadequate oxygenation. Surgical correction is emergent. -
Sequence similarities
Contains 1 DSL domain.
Contains 15 EGF-like domains. -
Developmental stage
Expressed in 32-52 days embryos in the distal cardiac outflow tract and pulmonary artery, major arteries, portal vein, optic vesicle, otocyst, branchial arches, metanephros, pancreas, mesocardium, around the major bronchial branches, and in the neural tube. -

Predicted band size: 134 kDa
Observed band size: 200, 23 kDa why is the actual band size different from the predicted?
Exposure time: 180 secondsBlocking buffer and concentration: 5% NFDM/TBST
Diluting buffer and concentration: 5% NFDM /TBSTNegative controls: Jurkat and MOLT-4 whole cell lysate (PMID: 30231940)
200-kDa full length and 23-kDa C-terminal JAG1 are observed. The molecular weights are consistent with what has been described in the literature (PMID: 30890522, 30890522).
This blot was developed using a high sensitivity ECL substrate.

Predicted band size: 134 kDa
Observed band size: 200 kDa why is the actual band size different from the predicted?Lanes 1 - 2: Merged signal (red and green). Green - ab109536 observed at 200 kDa. Red - loading control, ab9484, observed at 37 kDa.
ab109536 was shown to recognize in wild-type HAP1 cells as signal was lost at the expected MW in JAG1 knockout cells. Additional cross-reactive bands were observed in the wild-type and knockout cells. Wild-type and JAG1 knockout samples were subjected to SDS-PAGE. Ab109536 and ab9484 (Mouse anti GAPDH loading control) were incubated overnight at 4°C at 1/10000 dilution and 1/20000 dilution respectively. Blots were developed with Goat anti-Rabbit IgG H&L (IRDye® 800CW) preabsorbed ab216773 and Goat anti-Mouse IgG H&L (IRDye® 680RD) preabsorbed ab216776 secondary antibodies at 1/20000 dilution for 1 hour at room temperature before imaging.
