This gene and PCBP-2 have paralogues (PCBP3 and PCBP4) which are thought to have arisen as a result of duplication events of entire genes. The protein encoded by this gene appears to be multifunctional. It along with PCBP-2 and hnRNPK corresponds to the major cellular poly(rC)-binding protein. It contains three K-homologous (KH) domains which may be involved in RNA binding. This encoded protein together with PCBP-2 also functions as translational coactivators of poliovirus RNA via a sequence-specific interaction with stem-loop IV of the IRES and promote poliovirus RNA replication by binding to its 5'-terminal cloverleaf structure. It has also been implicated in translational control of the 15-lipoxygenase mRNA, human Papillomavirus type 16 L2 mRNA, and hepatitis A virus RNA. The encoded protein is also suggested to play a part in formation of a sequence-specific alpha-globin mRNP complex which is associated with alpha-globin mRNA stability.

In case of infection by poliovirus, plays a role in initiation of viral RNA replication in concert with the viral protein 3CD (PubMed:12414943). {ECO:0000269|PubMed:12414943}. |KH 1| |sequence-specific single stranded DNA binding| |viral RNA genome replication| |viral genome replication| |cytoplasmic ribonucleoprotein granule| |single-stranded DNA binding| |mRNA binding| |viral life cycle| |mRNA splicing, via spliceosome| |RNA splicing, via transesterification reactions with bulged adenosine as nucleophile| |RNA splicing, via transesterification reactions| |cadherin binding| |RNA splicing| |nuclear speck| |mRNA processing| |mRNA metabolic process| |viral process| |symbiotic process| |interspecies interaction between organisms| |RNA processing| |positive regulation of transcription by RNA polymerase II| |RNA binding| |positive regulation of transcription, DNA-templated| |DNA-binding transcription factor activity, RNA polymerase II-specific| |positive regulation of nucleic acid-templated transcription| |positive regulation of RNA biosynthetic process| |RNA metabolic process| |positive regulation of RNA metabolic process| |positive regulation of nucleobase-containing compound metabolic process| |positive regulation of macromolecule biosynthetic process| |positive regulation of cellular biosynthetic process| |positive regulation of gene expression| |membrane| |gene expression| |positive regulation of biosynthetic process| \\ === CRISPR Data === ^Screen^Score^ |[[:results:exp440|Aphidicolin 0.4μM R08 exp440]]|1.72| |[[:results:exp478|Doxorubicin 0.02μM R08 exp478]]|1.78| |[[:results:exp468|CB-5083 0.4μM R08 exp468]]|1.86| |[[:results:exp489|Hippuristanol 0.12μM R08 exp489 no dilution day6]]|1.92| |[[:results:exp502|Milciclib 2μM R08 exp502]]|1.95| |[[:results:exp524|Staurosporine 0.02μM R08 exp524]]|2.36| ^Gene^Correlation^ |[[:human genes:b:bak1|BAK1]]|0.417| Global Fraction of Cell Lines Where Essential: 675/739 ^Tissue^Fraction Of Cell Lines Where Essential^ |1290807.0|1/1| |909776.0|1/1| |bile duct|28/28| |blood|23/28| |bone|24/26| |breast|30/33| |central nervous system|53/56| |cervix|2/4| |colorectal|14/17| |esophagus|13/13| |fibroblast|1/1| |gastric|15/16| |kidney|18/21| |liver|17/20| |lung|67/75| |lymphocyte|14/16| |ovary|21/26| |pancreas|23/24| |peripheral nervous system|15/16| |plasma cell|13/15| |prostate|1/1| |skin|23/24| |soft tissue|9/9| |thyroid|2/2| |upper aerodigestive|21/22| |urinary tract|28/29| |uterus|3/5| == Essentiality in NALM6 == * **Essentiality Rank**: 361 * **Expression level (log2 read counts)**: 7.74 {{:chemogenomics:nalm6 dist.png?nolink |}}
