NP_010923.3

Ribosome-associated protein; involved along with heterodimeric partner Tma22p in recycling of 40S ribosomal subunits; involved in nonsense-mediated mRNA decay (NMD); contains a putative RNA binding domain; null mutant exhibits translation defects; localizes to the cytosol; has homology to human oncogene MCT-1; protein abundance increases in response to DNA replication stress
