Target/Specificity | This SAMD8 antibody is generated from rabbits immunized with a KLH conjugated synthetic peptide between 38-67 amino acids from the N-terminal region of human SAMD8. |
Dilution | WB~~1:1000 |
Format | Purified polyclonal antibody supplied in PBS with 0.09% (W/V) sodium azide. This antibody is purified through a protein A column, followed by peptide affinity purification. |
Storage | Maintain refrigerated at 2-8°C for up to 2 weeks. For long term storage store at -20°C in small aliquots to prevent freeze-thaw cycles. |
Precautions | SAMD8 Antibody (N-term) is for research use only and not for use in diagnostic or therapeutic procedures. |
Name | SAMD8 (HGNC:26320) |

Function | Synthesizes sphingolipids through transfer of a phosphatidyl head group from a glycerophospholipid on to the primary hydroxyl of a ceramide in the lumen of the endoplasmic reticulum (PubMed:19506037, PubMed:38388831). Catalyzes the synthesis of ceramide phosphoethanolamines (CPEs) (such as N-acylsphing-4-enine 1- phosphoethanolamine) by transferring phosphoethanolamine head group, which is smaller and more hydrophilic than the phosphocholine (PC) headgroup transferred in the canonical sphingomyelin synthesis (SMS) reaction by SMS1 or SMS2, from a phosphatidylethanolamine (1,2-diacyl- sn-glycero-3-phosphoethanolamine, PE) to a ceramide (such as N- acylsphing-4-enine) (PubMed:19506037, PubMed:38388831). The larger PC prevents an efficient fit in the enzyme's catalytic pocket, leading to little or no SMS activity (PubMed:19506037, PubMed:38388831). In vitro, in the absence of ceramide, it has PLC activity with preference for phosphatidylinositol and phosphatidic acid, but also hydrolyzes phosphatidylethanolamine (PubMed:33621517, PubMed:38388831). |
