It catalyzes the condensation of serine and palmitoyl-CoA yielding 3-ketodihydrosphingosine. This enzyme complex consists of subunits SPTLC1 SPTLC2 and sometimes SPTLC3 with a molecular weight around 53 kDa for SPTLC1. Expression of SPT is seen in various tissues including the liver and nervous system supporting its critical functions across the body.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nSerine palmitoyltransferase is involved in sphingolipid metabolism contributing to the formation of essential cellular components. It acts as a part of a larger enzyme complex responsible for generating sphingolipid precursors. These sphingolipids play a role in membrane structure and cell signaling affecting processes like cell growth and apoptosis. The enzyme therefore influences fundamental cellular phenomena demonstrating its widespread relevance in biochemistry and cell biology.\u003cbr\u003e\nPathways\u003cbr\u003e\nSerine palmitoyltransferase is vital in the de novo sphingolipid biosynthesis pathway where it initiates the creation of long-chain bases the core of most sphingolipids. It also links to the lipid metabolism pathway sharing interactions with proteins like ceramide synthase. By producing the starting materials for sphingolipids SPT integrates deeply into lipid regulation and signaling pathways affecting how cells communicate and respond to their environment.\u003cbr\u003e\nSerine palmitoyltransferase has connections to disorders like hereditary sensory and autonomic neuropathy type I (HSAN1) and metabolic syndromes. Mutations in the SPTLC1 subunit can lead to HSAN1 illustrating its direct involvement in nerve function and health. Additionally altered sphingolipid metabolism implicates SPT in metabolic syndromes where it interacts with proteins like ceramide influencing insulin resistance and lipid homeostasis. These connections emphasize the enzyme's significance in disease development and potential therapeutic targeting.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46847447662761,"sku":"ab143526","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/products\/abcam-ab143526","provider":"Iright","version":"1.0","type":"link"}
