Due to the research into this protein family, a wealth of data has been accumulated that keeps on growing. KLIFS\u2014Kinase\u2013Ligand Interaction Fingerprints and Structures\u2014is a structural database focusing on how kinase inhibitors interact with their targets. The aim of KLIFS is to support (structure-based) kinase research through the systematic collection, annotation, and processing of kinase structures. Now,\u00a05\u00a0years after releasing the initial KLIFS website, the database has undergone a complete overhaul with a new website, new logo, and new functionalities. In this article, we start by looking back at how KLIFS has been used by the research community, followed by a description of the renewed KLIFS, and conclude with showcasing the functionalities of KLIFS. Major changes include the integration of approved drugs and inhibitors in clinical trials, extension of the coverage to atypical kinases, and a RESTful API for programmatic access. KLIFS is available at the new domain https:\/\/klifs.net.<\/jats:p>","DOI":"10.1093\/nar\/gkaa895","type":"journal-article","created":{"date-parts":[[2020,9,30]],"date-time":"2020-09-30T12:36:32Z","timestamp":1601469392000},"page":"D562-D569","source":"Crossref","is-referenced-by-count":141,"title":["KLIFS: an overhaul after the first 5 years of supporting kinase research"],"prefix":"10.1093","volume":"49","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-9284-0802","authenticated-orcid":false,"given":"Georgi K","family":"Kanev","sequence":"first","affiliation":[{"name":"Division of Medicinal Chemistry, Amsterdam Institute for Molecules, Medicines and Systems (AIMMS), Vrije Universiteit Amsterdam, De Boelelaan 1108, 1081 HZ Amsterdam, The Netherlands"},{"name":"Department of Neurosurgery, Amsterdam University Medical Centers, Cancer Center Amsterdam, Brain Tumor Center Amsterdam, De Boelelaan 1117, 1081 HV Amsterdam, The Netherlands"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1226-2150","authenticated-orcid":false,"given":"Chris","family":"de\u00a0Graaf","sequence":"additional","affiliation":[{"name":"Sosei Heptares, Steinmetz Building, Granta Park, Great Abington, Cambridge, CB21 6DG, UK"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-9898-9616","authenticated-orcid":false,"given":"Bart A","family":"Westerman","sequence":"additional","affiliation":[{"name":"Department of Neurosurgery, Amsterdam University Medical Centers, Cancer Center Amsterdam, Brain Tumor Center Amsterdam, De Boelelaan 1117, 1081 HV Amsterdam, The Netherlands"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1969-0238","authenticated-orcid":false,"given":"Iwan J P","family":"de\u00a0Esch","sequence":"additional","affiliation":[{"name":"Division of Medicinal Chemistry, Amsterdam Institute for Molecules, Medicines and Systems (AIMMS), Vrije Universiteit Amsterdam, De Boelelaan 1108, 1081 HZ Amsterdam, The Netherlands"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5514-6021","authenticated-orcid":false,"given":"Albert J","family":"Kooistra","sequence":"additional","affiliation":[{"name":"Department of Drug Design and Pharmacology, University of Copenhagen, Universitetsparken 2, 2100 Copenhagen, Denmark"}]}],"member":"286","published-online":{"date-parts":[[2020,10,21]]},"reference":[{"key":"2021010313121353600_B1","doi-asserted-by":"crossref","first-page":"908","DOI":"10.3390\/molecules23040908","article-title":"PKIDB: a curated, annotated and updated database of protein kinase inhibitors in clinical trials","volume":"23","author":"Carles","year":"2018","journal-title":"Molecules"},{"key":"2021010313121353600_B2","doi-asserted-by":"crossref","first-page":"104609","DOI":"10.1016\/j.phrs.2019.104609","article-title":"Properties of FDA-approved small molecule protein kinase inhibitors: a 2020 update","volume":"152","author":"Roskoski","year":"2020","journal-title":"Pharmacol.
