slk

SLK or slk may refer to several distinct topics across different fields.

In automotive use, the Mercedes-Benz SLK is a two-seat roadster that has been produced in multiple generations since 1996. The model line is commonly known simply as the SLK, and it is characterized by a folding or retractable hardtop. The name is often said to derive from the German words Sportlich-Leicht-Kurz, meaning sporty, light, and short, reflecting the car’s design brief as a compact, performance-oriented roadster.

In biology, SLK is the gene symbol for STE20-like serine/threonine-protein kinase. In humans, the SLK enzyme belongs to the STE20 family and participates in signaling pathways that regulate the cytoskeleton, cell migration, and apoptosis. The gene is expressed in various tissues and has been investigated in cancer and developmental contexts.

In computing, SLK refers to a file extension associated with the SYLK (Symbolic Link) format, a plain-text spreadsheet interchange format used by historic spreadsheet programs such as Lotus 1-2-3 and early Microsoft Excel versions. SLK files encode cell values, formulas, and formatting using a line-based code. The format is largely of historical importance but can still appear in legacy data and conversions.
