General description

La-related protein 1 (UniProt: Q6PKG0; also known as La ribonucleoprotein domain family member 1) is encoded by the LARP1 (also known as KIAA0731, LARP) gene (Gene ID: 23367) in human. La-related protein 1 is a cytoplasmic RNA-binding protein that promotes translation of specific classes of mRNAs downstream of the mTORC1 complex. It contains 1 HTH La-type RNA-binding domain and it associates with the mRNA 5′cap in an mTOR-dependent manner and associates with mRNAs containing a 5′ terminal oligopyrimidine (5′TOP) motif, which is present in mRNAs encoding for ribosomal proteins and several components of the translation machinery. La-related protein 1 is also shown to associates with actively translating ribosomes via interaction with polyadenylate-binding protein 1 (PABPC1/PABP) and stimulates translation of mRNAs containing a 5′TOP, thereby regulating cell growth and proliferation. It is shown to be up-regulated in a number of hepatocellular carcinoma cell lines and liver cancer lesions, as well as in patients with hepatocellular carcinoma with a lower survival rate.
