What's a GeneRIF?

alternative translation initiation events appear to regulate relative expression of distinct SAPAP3 isoforms in different brain regions, which may function to influence synaptic plasticity.
Title: Synthesis of two SAPAP3 isoforms from a single mRNA is mediated via alternative translational initiation.
During the first postnatal week,PSD-95 immunoreactive strongly concentrated in the Purkinje cell layer.By P14, PSD-95 localized to many small puncta in the ML and to large clusters at mossy fiber rosettes in the glomerular layer.

RefSeqs maintained independently of Annotated Genomes

These reference sequences exist independently of genome builds. Explain

These reference sequences are curated independently of the genome annotation cycle, so their versions may not match the RefSeq versions in the current genome build. Identify version mismatches by comparing the version of the RefSeq in this section to the one reported in Genomic regions, transcripts, and products above.

mRNA and Protein(s)

NM_001276304.1 → NP_001263233.1 disks large-associated protein 3 isoform 2

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate in-frame splice site in the 3' coding region compared to variant 1. The resulting isoform (2) is shorter compared to isoform 1. The 5' UTR and 5' coding region for variant 2 are identical to those of variant 1 so the synthesis of two isoforms based on alternate in-frame translation starts discussed in PMID: 227619920 for variant 1 may also occur.
