Target
Function
Functions as a receptor for membrane-bound ligands Jagged1, Jagged2 and Delta1 to regulate
cell-fate determination. Upon ligand activation through the released notch intracellular domain
(NICD) it forms a transcriptional activator complex with RBPJ/RBPSUH and activates genes of
the enhancer of split locus. Affects the implementation of differentiation, proliferation and
apoptotic programs. May be important for normal lymphocyte function. In altered form, may
contribute to transformation or progression in some T-cell neoplasms. Involved in the maturation
of both CD4+ and CD8+ cells in the thymus. May be important for follicular differentiation and
possibly cell fate selection within the follicle. During cerebellar development, may function as a
receptor for neuronal DNER and may be involved in the differentiation of Bergmann glia.
Tissue specificity
In fetal tissues most abundant in spleen, brain stem and lung. Also present in most adult tissues
where it is found mainly in lymphoid tissues.
Involvement in disease
Defects in NOTCH1 are a cause of bicuspid aortic valve (BAV) [MIM:109730]. A common defect
in the aortic valve in which two rather than three leaflets are present. It is often associated with
aortic valve calcification and insufficiency. In extreme cases, the blood flow may be so restricted
that the left ventricle fails to grow, resulting in hypoplastic left heart syndrome.
Sequence similarities
Belongs to the NOTCH family.
Contains 5 ANK repeats.
Contains 36 EGF-like domains.
Contains 3 LNR (Lin/Notch) repeats.
Post-translational
modifications
Synthesized in the endoplasmic reticulum as an inactive form which is proteolytically cleaved by
a furin-like convertase in the trans-Golgi network before it reaches the plasma membrane to
yield an active, ligand-accessible form. Cleavage results in a C-terminal fragment N(TM) and a
N-terminal fragment N(EC). Following ligand binding, it is cleaved by TNF-alpha converting
enzyme (TACE) to yield a membrane-associated intermediate fragment called notch
extracellular truncation (NEXT). This fragment is then cleaved by presenilin dependent gammasecretase to release a notch-derived peptide containing the intracellular domain (NICD) from the
membrane.
Phosphorylated.
O-glycosylated on the EGF-like domains. Contains both O-linked fucose and O-linked glucose.
Ubiquitinated; undergoes 'Lys-29'-linked polyubiquitination catalyzed by ITCH.
Cellular localization
Cell membrane and Nucleus. Following proteolytical processing NICD is translocated to the
nucleus.

Notch1 was immunoprecipitated using 0.5mg
Hek293 whole cell extract, 5µg of Rabbit
polyclonal to Notch1 and 50µl of protein G
magnetic beads (+). No antibody was added
to the control (-).
The antibody was incubated under agitation

a further 10min under agitation.
Proteins were eluted by addition of 40µl SDS
loading buffer and incubated for 10min at
70°C; 10µl of each sample was separated on
a SDS PAGE gel, transferred to a
nitrocellulose membrane, blocked with 5%
BSA and probed with ab65297.

Predicted band size : 272 kDa
Observed band size : 120 kDa
Additional bands at : 160 kDa,50 kDa. We
are unsure as to the identity of these extra
bands.
Exposure time : 3 minutesThe band
observed at 120 kDa could potentially be a
truncated form of Notch1, following cleavage
by furin-like protease. This band is also
observed with other commercially available
antibodies to Notch1.
