Article: Biotechnology My Blog Title: The world, from the past to the present, retold from the timelines.
2023: Notable innovations: a large language model (ProGen) that could generate functional protein sequences with a predictable function, with the input including tags specifying protein properties. For example, sickle cell anemia is due to a single sequence change in which a single amino acid (the glutamic acid that is usually in the sixth position of the protein chain) is replaced by a valine, a branched-chain essential amino acid, in the Beta-globin subunit of the hemoglobin protein. Glutamic acid is an amino acid used to form proteins. Amyloid fibrils are formed by normally soluble proteins, which assemble to form insoluble fibers that are resistant to degradation. Their formation can accompany disease and each disease is characterized by a specific protein or peptide that aggregates. Lastly, crafting a grammatically correct but meaningless sentence bears some resemblance to protein structures that lack any discernible function or may even cause disease, as in the case of amyloid fibrils. Proteins and natural languages also present differences that need to be taken into account in their processing. In human languages, the alphabet contains many symbols (like uniform punctuation and stop words) (Ofer et al., 2021). In contrast, the alphabet of protein language adopted a simpler alphabet of 20 characters. Nevertheless the letters of proteins can be modified to alter their function, e.g., through methylation of lysine residues, phosphorylation, ubiquitination and other post-translational modifications, thus adding complexity to the protein language. Methylation of lysine residues has emerged as one of the major posttranslational modifications (PTMs) in histone proteins. A histone is a protein that provides structural support for a chromosome. Phosphorylation is an extremely common posttranslational modification of proteins and it regulates the activity of one or more proteins along most signaling pathways. Ubiquitination is a versatile post-translational modification (PTM), which regulates diverse fundamental features of protein substrates, including stability, activity, and localization. The language of proteins could be described by the use of stochastic or randomness context-free grammars (Dyrka and Nebel, 2009) for covering any higher-order dependencies such as nested and crossing relationships that are common in proteins. Human languages define words clearly in written texts, but protein “word boundaries” are less evident because we do not always know a priori if a certain sequence is related to a function (e.g., it is part of a domain or motif); a priori means “what comes first.” One possibility was to use the secondary structure for splitting the sentences into words or to exploit sub-word segmentation that did not require any predefined knowledge of words in the protein language. However, the tokenization process would require exploiting the tertiary structure with more intensive calculations. Protein tertiary structure is the three-dimensional shape of a protein. The overall understanding of the protein language was limited, requiring extensive experimental tests to identify its functionalities.
