LARP1 - La ribonucleoprotein 1, translational regulator Gene

Also Known as LARP; Lar1; Lhp1

Species: Homo sapiens

Gene Type: protein coding

Gene ID: 23367

About LARP1

Cytogenetic location: 5q33.2 Genomic coordinates (GRCh38): 5:154,682,979-154,817,605 (from NCBI)

This gene has 20 transcripts (splice variants), 208 orthologues and 6 paralogues. Ubiquitous expression in thyroid (RPKM 29.3), brain (RPKM 25.2) and 25 other tissues.

Summary

Enables eukaryotic initiation factor 4E binding activity; nucleic acid binding activity; and ribosomal small subunit binding activity. Involved in several processes, including TORC1 signaling; cellular response to rapamycin; and posttranscriptional regulation of gene expression. Located in cytoplasmic stress granule. Colocalizes with TORC1 complex and polysomal ribosome. [provided by Alliance of Genome Resources, Apr 2022]
