ACTL11P是一个假基因，属于肌动蛋白样基因家族（actin-like gene family）。假基因通常是由功能基因复制或逆转录转座产生的非功能性DNA序列，缺乏完整的编码能力或调控元件，因此不产生功能性蛋白质。ACTL11P与功能性肌动蛋白基因（如ACTB、ACTG1等）有较高的序列相似性，但因其含有终止密码子、移码突变或其他缺陷而失去功能。肌动蛋白家族成员广泛参与细胞骨架形成、细胞运动、胞质分裂等关键生物学过程，但ACTL11P作为假基因可能仅保留部分序列特征而不具备这些功能。目前关于ACTL11P的具体作用研究较少，假基因通常被认为可能通过转录调控或作为竞争性内源RNA（ceRNA）间接影响其他基因的表达。例如，某些假基因可通过与microRNA结合来调节其靶基因的活性。ACTL11P若发生突变可能不会直接影响机体功能，但假基因的异常表达有时会干扰相关功能基因的调控网络。该基因的过表达或低表达对机体的影响尚不明确，但假基因的异常表达可能与某些疾病（如癌症）中基因调控紊乱有关。肌动蛋白样基因家族的共性包括编码结构相似的蛋白质，这些蛋白参与维持细胞形态、细胞内运输和信号转导等过程。需要注意的是，ACTL11P作为假基因的功能意义仍需更多实验验证，其与疾病的潜在关联也待进一步探索。

ACTL11P is a pseudogene that belongs to the actin-like gene family, a group of genes encoding proteins structurally similar to actin, which are fundamental to cellular architecture and dynamics. As a non-functional genomic sequence, ACTL11P likely arose from the duplication or retrotransposition of a functional actin gene, such as ACTB or ACTG1, but has since accumulated disabling mutations, including premature stop codons and frameshifts, that prevent the production of a functional protein. While its parent genes play critical roles in cytoskeletal formation, cell motility, cytokinesis, intracellular transport, and signal transduction, ACTL11P lacks the intact coding capacity and regulatory elements necessary to perform these biological tasks. Despite its lack of direct protein function, emerging evidence suggests that pseudogenes like ACTL11P may exert indirect regulatory effects by acting as competitive endogenous RNAs (ceRNAs), potentially sequestering microRNAs and thereby modulating the expression of other target genes. Although the specific physiological impact of ACTL11P mutations is currently unclear and likely minimal in direct terms, its aberrant expression could disrupt the regulatory networks governing related functional actin genes. Consequently, while the precise disease relevance of ACTL11P remains to be fully elucidated, its dysregulation may contribute to the complex gene expression disorders observed in certain pathological conditions, such as cancer, highlighting the need for further experimental investigation into its potential role in cellular homeostasis.
