A notch filter is a band-stop filter with a very narrow stopband that rejects a narrow frequency band, such as 50 or 60 Hz mains hum.
Notch signaling pathway
Notch signaling pathway: conserved animal cell-cell communication system using Notch receptors (NOTCH1-4), Delta/Jagged ligands, ADAM and gamma-secretase cleavage, NICD/CSL/MAML transcription; roles in development, cancer, Alagille syndrome.
Notch, C-terminal
Notch, C-terminal (InterPro IPR024600, Notch_C) is a conserved protein domain at the C-terminal end of Notch receptors, covering the NICD region with the TAD, NLS, and PEST degrons; PEST deletions link to T-cell leukemia and the region drives Notch condensate formation.
Notch, NODP domain
NODP domain (Pfam PF07684, IPR011656) of the Notch receptor, adjacent to the NOD domain; function unknown, an Eumetazoan innovation, present in NOTCH1-4 and homologs, linked to NOTCH1 leukemia mutations.
NOTCH1
NOTCH1 (notch receptor 1, TAN-1) is a human chromosome 9q34.3 gene encoding a 2,555-amino-acid Notch family transmembrane receptor for JAG1/JAG2/DLL1 ligands; activated by cleavage to NICD, it drives transcription, T-cell development, and is mutated in 55-60% of T-ALL.
NOTCH3
NOTCH3 (Neurogenic Locus Notch Homolog Protein 3), gene at 19p13.1 encoding a vascular smooth muscle transmembrane receptor with 34 EGF-like repeats; cysteine-altering mutations cause CADASIL, the leading hereditary cerebral small vessel disease.
NOTCH4
NOTCH4 (INT3, HGNC:7884) is a human Notch receptor gene on 6p21.32, preferentially expressed in endothelium; linked to arteriovenous malformations, tumor angiogenesis, and systemic sclerosis.

Note-taking
Note-taking records information from lectures or texts for later review, serving an encoding function during capture and an external-storage function afterward. Key evidence covers generative versus verbatim notes, the laptop versus longhand debate, accessibility accommodations, and AI note-taking tools.
Notebook
A notebook, or notepad, is a bound collection of paper pages used for writing, drawing, or recording data, ranging from school exercise books to legal records.
Notebook (2019 film)
