該基因編碼LIM結構域蛋白亞家族的一個成員，其特征是N端富含脯氨酸區域和3個C端LIM結構域編碼蛋白定位于細胞周圍的局灶性粘連，可能與細胞粘附和細胞運動有關。這種蛋白質也通過細胞核穿梭，并可能作為轉錄輔激活劑發揮作用。該基因位于某些與疾病相關的染色體易位的接合處，導致可能促進腫瘤生長的嵌合蛋白的表達。選擇性剪接導致多個轉錄變體[由RefSeq提供，2014年7月]
This gene encodes a member of a subfamily of LIM domain proteins that are characterized by an N-terminal proline-rich region and three C-terminal LIM domains. The encoded protein localizes to the cell periphery in focal adhesions and may be involved in cell-cell adhesion and cell motility. This protein also shuttles through the nucleus and may function as a transcriptional co-activator. This gene is located at the junction of certain disease-related chromosomal translocations, which result in the expression of chimeric proteins that may promote tumor growth. Alternative splicing results in multiple transcript variants. [provided by RefSeq, Jul 2014]
