HCCS Antibody

1. Data suggest that although HCCS mediates heme attachment to N-terminal cysteine in heme-attachment site (CXXXH) of cytochrome C variants, up to 50% of cytochrome C produced is modified in an oxygen-dependent manner, resulting in a mixed population of cytochrome c. [HCCS = holocytochrome c synthase] PMID: 28617588
2. Bacterial cyt c biogenesis pathways (Systems I and II) appear to recognize simply the CXXCH motif, not requiring alpha helix-1. Results here explain mechanistically how HCCS (System III) requires an extended region adjacent to CXXCH for maturation. PMID: 27387500
3. cysteines and histidine of the heme attachment site, Cys-XX-Cys-His play a key role in mitochondrial holocytochrome c synthase PMID: 25170082
4. These data indicate that heme contacts mediated by residues within these domains modulate the dynamics of heme binding and contribute to the stability of the HCCS-heme-cytochrome c steady state ternary complex. PMID: 25054239
5. Identification of a deletion in two patients, including HCCS, leads to the diagnosis of microphthalmia with linear skin defects syndrome PMID: 23401659
6. Spectroscopic analyses of HCCS alone and complexes of HCCS with site-directed variants of cytochrome c revealed the fundamental steps of heme attachment and maturation. PMID: 23150584
7. Through the study of genetically engineered mice, the loss of HCCS is demonstrated to cause the male lethality of microphthalmia with linear skin defects (MLS) syndrome. PMID: 12444108
8. mutant proteins (R217C and Delta 197-268) were unable to complement a Saccharomyces cerevisiae mutant deficient for the HCCS orthologue Cyc3p, in contrast to wild-type HCCS PMID: 17033964
9. Missense mutation p.E159K of HCCS, leading to loss-of-function of encoded holocytochrome c-type synthase, in female with microphthalmia of both eyes and bilateral sclerocornea may suggest HCCS as candidate for severe ocular manifestations. PMID: 17893649
