PCSKperhe

PCSKperhe is a term used in Finnish to refer to the family of proprotein convertase subtilisin/kexin type (PCSK) enzymes. This family consists of several members, including PCSK1 (also known as PC1/3), PCSK2 (PC2), PCSK3 (furin), PCSK4 (PC4), PCSK5 (PC5/6), PCSK6 (PC7), PCSK7 (PC8), PCSK8 (kexin 1), and PCSK9. These enzymes are serine proteases that play crucial roles in the post-translational processing of various proteins. They are responsible for cleaving precursor proteins into their active forms, a process essential for a wide range of biological functions.

The PCSK enzymes are involved in diverse physiological processes, including hormone production, neurotransmitter synthesis, viral maturation, and cell growth and differentiation. For example, PCSK1 is critical for the processing of prohormones like proinsulin and proopiomelanocortin. PCSK2 is important for the activation of neuropeptides. PCSK3 (furin) is widely expressed and participates in the activation of numerous substrates, including growth factors and viral envelope proteins. Dysfunction or mutations in PCSK genes can lead to various human diseases, underscoring their vital importance in maintaining health. Research into the PCSKperhe continues to uncover new roles and therapeutic targets related to these enzymes.
