CC   -!- SUBCELLULAR LOCATION: Secreted {ECO:0000250|UniProtKB:P02654}.
CC   -!- MISCELLANEOUS: Apolipoprotein C-I is present in acidic (APOC1A) and
CC       basic (APOC1B) forms in P.paniscus, P.abelii and P.troglodytes and
CC       perhaps also in baboons and macaques. The two genes for ApoC-I arose
CC       through a duplication process that occurred after the divergence of New
CC       World monkeys from the human lineage. In human, the acidic form has
CC       become a pseudogene sometime between the divergence of bonobos and
CC       chimpanzees from the human lineage and the appearance of the
CC       Denisovans. Pseudogenization resulted when the codon for the
CC       penultimate amino acid in the signal sequence was changed to a stop
CC       codon. {ECO:0000303|PubMed:25160599}.
CC   -!- SIMILARITY: Belongs to the apolipoprotein C1 family. {ECO:0000305}.
