Instead, the study detailed in that abstract focuses on keratinocyte biology—specifically, on how keratinocytes internalize melanosomes from melanocytes and retain them in the perinuclear region, where a group of Rab family small GTPases is enriched. The work identifies several Rab proteins associated with these melanosome‐containing compartments and, in particular, highlights Rab7B/42 as a key facilitator of protein degradation on incorporated melanosomes, a process that likely contributes to protecting nuclear DNA against ultraviolet injury."}, {"type": "fg", "children": [{"type": "fg_f", "ref": "1"}]}, {"type": "t", "text": ""}]}, {"type": "rg", "children": [{"type": "r", "ref": 1, "children": [{"type": "t", "text": "Soujiro Marubashi, Mitsunori Fukuda "}, {"type": "b", "children": [{"type": "t", "text": "Rab7B/42 Is Functionally Involved in Protein Degradation on Melanosomes in Keratinocytes."}]}, {"type": "t", "text": " "}, {"type": "i", "children": [{"type": "t", "text": "Cell Struct Funct (2020)"}]}, {"type": "t", "text": " DOI: "}, {"type": "a", "children": [{"type": "t", "text": "10.1247/csf.19039"}], "href": "https://doi.org/10.1247/csf.19039"}, {"type": "t", "text": " PMID: "}, {"type": "a", "children": [{"type": "t", "text": "32037382"}], "href": "https://pubmed.ncbi.nlm.nih.gov/32037382"}]}]}]}
