HAPLN2 also known as hyaluronan and proteoglycan link protein 2 is a component of the extracellular matrix involved in stabilizing the structure of cartilage and other tissues. It has a molecular mass of approximately 41 kDa. Researchers have found HAPLN2 expression in the brain particularly in regions like the synaptic sites. It plays a part in maintaining the integrity of the perineuronal net a specialized extracellular matrix structure surrounding neurons.
Biological function summary
HAPLN2 maintains the architecture of the extracellular matrix by binding to hyaluronan and proteoglycans. This binding enhances tissue resilience and elasticity essential for normal brain function. HAPLN2 does not work alone; it forms a complex with other matrix molecules like aggrecan contributing to the matrix's stability and biological activity. This complex formation is vital for preserving tissue homeostasis and supporting cellular interactions.
Pathways
HAPLN2 contributes to extracellular matrix organization and neural development pathways. It interacts closely with proteins such as tenascin-R which play roles in guiding neural cell adhesion and migration. These pathways ensure proper neuron connectivity and repair mechanisms in the central nervous system facilitating normal development and plasticity.
HAPLN2's dysregulation connects to conditions like schizophrenia and glioblastoma. In schizophrenia altered HAPLN2 expression affects the structural properties of the perineuronal nets impacting synaptic stability and signaling. Researchers also note its connections with matrix metalloproteinases in glioblastoma as these enzymes can degrade HAPLN2 influencing tumor invasion and progression through the remodeling of the extracellular matrix.
