The Karataş Protein–Personality Model (KPPM) proposes a theoretical framework linking protein expression patterns to stable personality traits and behavioral dynamics. Drawing from molecular biology, systems neuroscience, and personality psychology, KPPM suggests that variations in protein synthesis, regulation, and interaction networks may form biological signatures that influence perception, emotional regulation, and long-term behavioral tendencies. The model outlines how protein-based signaling pathways might create individualized cognitive-emotional profiles, contributing to differences in temperament, adaptability, stress response, and interpersonal behavior. By integrating biological and psychological perspectives, KPPM offers a novel hypothesis aimed at bridging the gap between cellular-level processes and higher-order personality constructs. This framework is intended to stimulate interdisciplinary research exploring the biological foundations of personality.
