NMD features

SMOX

Spermine oxidase

2.1

6.1E−10

SMOX is a regulator of polyamine metabolism and may be involved in neurodegenerative diseases.

uORF

OSBP2

Oxysterol-binding protein 2

2.2

3.3E−8

OSBP2 is involved in lipid transport. It binds to oxysterols and may inhibit their cytotoxicity. It is essential for cell proliferation and survival.

uORF

GPX3

Glutathione peroxidase 3

2.4

2.7E−5

GPX3 protects cells and enzymes from oxidative damage.

uORF

RAP1GAP

RAP1 GTPase activating protein

4.0

0.0098

RAP1GAP is the most prominent GTPase-activating protein in brain. It is involved in neuronal differentiation.

uORF

HEY1

Hes-related family bHLH transcription factor with YRPW motif 1

2.0

0.012

HEY1 is a transcriptional repressor in the Notch signaling pathway which plays an important role in gliogenesis, cardiac morphogenesis and angiogenesis.

uORF

G0S2

G0/G1 switch 2

2.6

0.012

G0S2 promotes apoptosis.

uORF

GCAT

Glycine C-acetyltransferase

2.0

0.015

GCAT is the second mitochondrial enzyme in a 2-step reaction that converts L-threonine to glycine.

uORF

MAP1B

Microtubule-associated protein 1B

2.9

0.020

Dominant germline mutations cause periventricular nodular heterotopia (MIM 618918). MAP1B is involved in microtubule assembly, which is an essential step in neurogenesis.

uORF, long 3′UTR, AS

SYNM

Synemin

2.0

0.033

SYNM plays an important cytoskeletal role within the muscle cell cytoskeleton. SYNM is a candidate gene for dilated cardiomyopathy.

uORF, long 3′UTR

ZNF155

Zinc finger protein 155

−2.3

6.1E−10

ZNF155 may be involved in transcriptional regulation.

uORF

OLFM1

Olfactomedin 1

−2.4

0.012

OLFM1 contributes to the regulation of axonal growth in the embryonic and adult central nervous system.

uORF

RAVER2

Ribonucleoprotein, PTB-binding 2

−2.3

0.020

RAVER2 may bind single-stranded nucleic acids.

uORF, long 3′UTR, AS

NTSR1

Neurotensin receptor 1

−2.0

0.023

NTSR1 mediates the multiple functions of neurotensin in the brain.

uORF long 3′UTR

TUBB2A

Tubulin beta 2A class IIa

−2.9

0.050

TUBB2A is the major constituent of microtubules. Dominant germline mutations cause cortical dysplasia (MIM 615763).
