Summary: The protein encoded by this gene belongs to the class-3 semaphorin/collapsin family, whose members function in growth cone guidance during neuronal development. This family member inhibits axonal extension and has been shown to act as a tumor suppressor by inducing apoptosis. Alternative splicing of this gene results in multiple transcript variants.

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.

See identical proteins and their annotated locations for NP_001005914.1

Status: REVIEWED

Description

Transcript Variant: This variant (2) uses an alternate in-frame splice site in the central coding region, compared to variant 1, resulting in an isoform (2) that is 1 aa shorter than isoform 1. The 5' terminal exon of this variant is inferred based on tiled partial transcript alignments.

Description

Transcript Variant: This variant (5) lacks several 5' exons but contains alternate 5' exon structure, and it thus differs in its 5' UTR and initiates translation from a downstream in-frame start codon, compared to variant 1. The encoded isoform (4) is shorter at the N-terminus, compared to isoform 1. Both variants 5 and 6 encode isoform 4.
