K1R

K1R is an alphanumeric designation that appears in different domains, and there is no single, universal meaning attached to it. The precise interpretation depends on the context in which it is used, such as biology, technology, or cataloging.

In biology and biochemistry, K1R may be encountered as a shorthand notation for a protein sequence change, indicating a substitution from lysine (K) to arginine (R) at a specified residue. In scientific writing, the position and the name of the gene or protein are essential for clarity; without that context, K1R is ambiguous.

In technology and consumer products, K1R frequently serves as a model number, part designation, or catalog code. It may appear on devices, components, or accessories, with the exact specifications and features varying by manufacturer and product line. When seen in such contexts, the accompanying documentation or product page provides the definitive details.

K1R can also function as a general shorthand label in documentation, event codes, or dataset identifiers. Because alphanumeric codes are reused across disciplines, a precise definition requires the relevant domain, source, or accompanying description.

If a specific domain or context for K1R is known, that information can guide toward a definitive article or source. Providing the relevant field (for example, biology, electronics, or cataloging) will help identify the exact meaning and any associated historical or technical details.
