NCK2 (NCK Adaptor Protein 2): NCK2 is a protein that links receptor tyrosine kinases to signalling pathways regulating cell growth, movement, and cytoskeletal organisation. It participates in multiple signalling networks that enable cells to respond to external stimuli. Dysregulation of NCK2 has been associated with cancer progression and metastasis, highlighting its role in cell signalling and tumour development.
