Summary: Predicted to enable double-stranded RNA binding activity and translation initiation factor activity. Predicted to be involved in cytoplasmic translational initiation and positive regulation of transcription by RNA polymerase II. Predicted to be located in nuclear stress granule; perinuclear region of cytoplasm; and plasma membrane. Is expressed in several structures, including central nervous system; liver; lung; ovary; and sensory organ. Orthologous to human EIF4A1 (eukaryotic translation initiation factor 4A1).

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_001152847.1

Status: VALIDATED

Description

Transcript Variant: This variant (2) uses an alternate splice site in the 3' coding region that results in a frameshift, compared to variant 1. The resulting isoform (2) has a shorter and distinct C-terminus, compared to isoform 1.
