General annotation (Comments)

Function

Involved in translation termination in response to the termination codons UAA, UAG and UGA. Stimulates the activity of ERF1. Involved in regulation of mammalian cell growth. Component of the transient SURF complex which recruits UPF1 to stalled ribosomes in the context of nonsense-mediated decay (NMD) of mRNAs containing premature stop codons.

Subunit structure

Component of the transient SURF (SMG1-UPF1-eRF1-eRF3) complex.

Sequence similarities

Belongs to the GTP-binding elongation factor family. ERF3 subfamily.

Caution

eRF3 antibodies used in Ref.4 do not differentiate between GSPT1/ERF3A and GSPT2/ERF3B.

Alternative products

This entry describes 2 isoforms produced by alternative splicing. [Align] [Select]
Isoform 1 (identifier: P15170-1)

This isoform has been chosen as the 'canonical' sequence. All positional information in this entry refers to it. This is also the sequence that appears in the downloadable versions of the entry.
Isoform 2 (identifier: P15170-2)

The sequence of this isoform differs from the canonical sequence as follows:
     1-1: M → MDPGSGGGGG...CEGSNSAVSM
     8-8: Missing.
Note: Ref.3 (AAH09503) sequence is in conflict in position: 6-9:GGGG->G, 92:G->C, 100:V->A.
