LOC646405 Activateurs

LOC646405 is a provisional designation used in genomic databases for a gene locus that has not yet been fully characterized or may not correspond to a known protein-coding gene. This kind of designation is common in genomic annotation projects where automated computational tools predict the existence of a gene based on DNA sequences, but experimental evidence to confirm the gene's function, the existence of the protein, or its biological role is lacking or incomplete.

The "LOC" prefix indicates "locus," suggesting a specific location within the genome, while the numbers that follow serve as a unique identifier. In the case of LOC646405, it implies that this sequence is the 646,405th locus entered into a particular database. The annotation might be found in genomic sequencing projects such as the Human Genome Project or other organismal sequencing efforts.The characterization of such loci can involve various experimental approaches, including transcript profiling to detect RNA expression, proteomic studies to identify the protein product, and functional assays to determine the biological role of the protein. Additionally, comparative genomics can provide clues about the function of the protein by identifying homologous genes in other species.
