Y14

Y14 is an alphanumeric designation used in several unrelated fields, so it does not point to a single concept on its own. In practice, the meaning of Y14 depends on the context in which it appears.

In biology, Y14 refers to a protein component of the exon junction complex, commonly known as the Y14 protein. This protein is encoded by the RBM8A gene and participates in mRNA processing, including splicing, export from the nucleus, and surveillance mechanisms such as nonsense-mediated decay. The Y14 protein is conserved across eukaryotes and works with other EJC components to influence the fate of transcripts after splicing.

In engineering and manufacturing, Y14 denotes a family of standards published by the American Society of Mechanical Engineers (ASME) for engineering drawings and related documentation. The most widely cited member is ASME Y14.5, which governs dimensioning and tolerancing to ensure clear and consistent communication of part geometry. Other Y14 standards address topics such as drawing symbols, data management, and documentation practices, with revisions reflecting advances in technology and industry practice.

Beyond biology and engineering, Y14 can appear as a model number, project code, or catalog designation in various industries. In such cases, the precise meaning is specific to the organization or product line involved, and without additional context, it can refer to anything from a variant of a device to an internal reference code.
