功能概要

犰狳样蛋白的特征在于一系列犰狳重复序列，首先在果蝇“犰狳”基因产物中定义，其长度通常为 42 至 45 个氨基酸。这些蛋白质可以根据它们的重复次数、整体序列相似性以及重复序列在整个序列中的分布情况分为亚家族。犰狳样蛋白的 p120 (ctn) /plakophilin 亚家族成员，包括 CTNND1、CTNND2、PKP1、PKP2、PKP4 和 ARVCF。 PKP4 可能是桥粒斑块和其他粘附斑块的组成部分，并被认为参与调节连接斑块组织和钙粘蛋白功能。已发现该基因编码不同异构体的多个转录变体。[RefSeq 提供，2015 年 2 月]

Armadillo-like proteins are characterized by a series of armadillo repeats, first defined in the Drosophila 'armadillo' gene product, that are typically 42 to 45 Amino acids in length. These proteins can be divided into subfamilies based on their number of repeats, their overall sequence similarity, and the dispersion of the repeats throughout their sequences. Members of the p120(ctn)/plakophilin subfamily of Armadillo-like proteins, including CTNND1, CTNND2, PKP1, PKP2, PKP4, and ARVCF. PKP4 may be a component of desmosomal plaque and other adhesion plaques and is thought to be involved in regulating junctional plaque organization and cadherin function. Multiple transcript variants encoding different isoforms have been found for this gene. [provided by RefSeq, Feb 2015]
