Summary: The protein encoded by this gene is a ubiquitous actin monomer-binding protein belonging to the profilin family. It is thought to regulate actin polymerization in response to extracellular signals. There are two alternatively spliced transcript variants encoding different isoforms described for this gene.

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.

NM_002628.5 → NP_002619.1 profilin-2 isoform b

See identical proteins and their annotated locations for NP_002619.1

Status: REVIEWED

Description

Transcript Variant: This variant (2) lacks an internal segment in the 3' region including 3' coding region and 3' UTR, resulting in a downstream stop codon and a shorter 3' UTR, as compared to variant 1. The encoded isoform (b) is the same length but has a different C-terminus compared to isoform a.
