Binds tenaciously to poly(C) sequences. Likely to play a role in the nuclear metabolism of hnRNAs, particularly for pre-mRNAs that contain cytidine-rich sequences. Can also bind poly(C) single-stranded DNA. Plays an important role in p53/TP53 response to DNA damage, acting at the level of both transcription activation and repression. When sumoylated, acts as a transcriptional coactivator of p53/TP53, playing a role in p21/CDKN1A and 14-3-3 sigma/SFN induction. As far as transcription repression is concerned, acts by interacting with long intergenic RNA p21 (lincRNA-p21), a non-coding RNA induced by p53/TP53. This interaction is necessary for the induction of apoptosis, but not cell cycle arrest. As part of a ribonucleoprotein complex composed at least of ZNF827, HNRNPL and the circular RNA circZNF827 that nucleates the complex on chromatin, may negatively regulate the transcription of genes involved in neuronal differentiation"],"length":464,"sequence":"METEQPEETFPNTETNGEFGKRPAEDMEEEQAFKRSRNTDEMVELRILLQSKNAGAVIGKGGKNIKALRTDYNASVSVPDSSGPERILSISADIETIGEILKKIIPTLEEGLQLPSPTATSQLPLESDAVECLNYQHYKGSDFDCELRLLIHQSLAGGIIGVKGAKIKELRENTQTTIKLFQECCPQSTDRVVLIGGKPDRVVECIKIILDLISESPIKGRAQPYDPNFYDETYDYGGFTMMFDDRRGRPVGFPMRGRGGFDRMPPGRGGRPMPPSRRDYDDMSPRRGPPPPPPGRGGRGGSRARNLPLPPPPPPRGGDLMAYDRRGRPGDRYDGMVGFSADETWDSAIDTWSPSEWQMAYEPQGGSGYDYSYAGGRGSYGDLGGPIITTQVTIPKDLAGSIIGKGGQRIKQIRHESGASIKIDEPLEGSEDRIITITGTQDQIQNAQYLLQNSVKQYADVEGF","proteome":"UP001732780","gene":"HNRNPK","go_terms":[{"identifier":"GO:0003723","name":"RNA binding","category":{"code":"F","name":"molecular_function"}},{"identifier":"GO:0003676","name":"nucleic acid binding","category":{"code":"F","name":"molecular_function"}}],"protein_evidence":4,"source_database":"unreviewed","is_fragment":false,"in_alphafold":true,"in_bfvd":false,"ida_accession":"0f680ec6759e2a13fb19f9d7aed5e3e0c0bd5d3f","counters":{"domain_architectures":1770,"entries":14,"isoforms":0,"proteomes":1,"sets":2,"structures":0,"taxa":1,"dbEntries":{"pfam":2,"ssf":1,"smart":1,"cathgene3d":1,"profile":1,"cdd":3,"panther":1,"interpro":4},"proteome":1,"taxonomy":1,"similar_proteins":1770}}}
