Src

Src is a term used in multiple fields with distinct meanings.

In computing, src commonly denotes the source code directory within a project. The src directory typically contains the human-readable code that is compiled or transformed to create executables, libraries, or other artifacts. This naming convention is widespread across programming languages and build systems, with other directories such as bin or build holding compiled outputs. In web development, the src attribute of HTML elements specifies the location of a resource, such as the URL of an image, script, iframe, or video.

In biology, Src refers to a proto-oncogene that encodes a non-receptor protein tyrosine kinase belonging to the Src family. The discovery of the viral counterpart v-Src from Rous sarcoma virus helped establish the importance of tyrosine kinases in signal transduction. The human SRC gene encodes a cytoplasmic and membrane-associated kinase involved in regulating processes such as cell growth, differentiation, and survival. Dysregulation or overactivity of Src family kinases has been linked to cancer, and several inhibitors targeting these kinases are used in cancer therapy.

As an acronym, SRC can stand for various organizations and concepts depending on context, including scientific or research councils, strategic resource centers, or other institutional names. In most technical contexts, src is interpreted by its domain-specific meaning—directory name in computing or a gene/protein in biology.
