It weighs approximately 57 kDa and is known for its expression in diverse cell types especially in the nucleus of eukaryotic cells. PTBP1 contains four RNA recognition motifs which allow it to interact with polypyrimidine-rich sequences in pre-mRNA. This interaction plays an important role in RNA splicing and the regulation of alternative splicing events.\u003cbr\u003e\nBiological function summary\u003cbr\u003e\nPTBP1 influences the stability transport and translation of mRNA molecules. It is part of the heterogeneous nuclear ribonucleoprotein complex which plays a fundamental role in the processing and modification of pre-mRNA into mature mRNA. This activity impacts the expression of a wide range of genes affecting cellular function and growth. PTBP1 regulates mRNA metabolism contributing significantly to post-transcriptional gene regulation.\u003cbr\u003e\nPathways\u003cbr\u003e\nThe involvement of PTBP1 spans the management of alternative splicing and the modulation of gene expression. It participates importantly in the alternative splicing pathway alongside proteins like PTBP2 which perform overlapping functions in neurons. PTBP1 affects exon inclusion or exclusion influencing the genetic diversity presented in protein forms within cells. It also plays a role in the exon junction complex pathway impacting post-translational modifications and protein interactions.\u003cbr\u003e\nVariations in PTBP1 function are linked to conditions such as cancer and neurological disorders. Altered expression levels or mutations can contribute to carcinogenesis through the misregulation of splice variants specific to oncogenes and tumor suppressor genes. In neurological disorders PTBP1 interacts with proteins like FUS affecting the regulation of neuronal-specific alternative splicing. Misbalance in these interactions can have significant pathological implications contributing to diseases such as amyotrophic lateral sclerosis (ALS) and glioblastomas.\u003c\/p\u003e","brand":"Abcam","offers":[{"title":"Default Title","offer_id":46845083418793,"sku":"ab265155","price":0.99,"currency_code":"USD","in_stock":true}],"url":"https:\/\/iright.com\/es\/products\/abcam-ab265155","provider":"Iright","version":"1.0","type":"link"}
