α-輔肌動蛋白2（英語：Alpha-actinin-2）是一種蛋白質，在人類中由ACTN2基因編碼。^[6]該基因編碼一種在骨骼肌和心肌中表達的α-輔肌動蛋白異構體，其功能是將肌原纖維肌動蛋白細絲和肌聯蛋白錨定到Z盤上。

結構[編輯]

α-輔肌動蛋白2是一種103.8kDa的蛋白質，由894個氨基酸組成。^[7]^[8]每個分子都是棒狀的（長度為35nm），並且以反平行的方式同源二聚化。每個單體都有一個N端肌動蛋白結合區，由兩個鈣調理蛋白同源結構域、兩個C端 EF手結構域和四個串聯血影蛋白樣重複序列組成，形成分子中心區域的杆狀結構域。^[9] 人類α-輔肌動蛋白2在3.5Å處的高解像度晶體結構最近得到解決。^[10]α輔肌動蛋白屬於血影蛋白基因超家族，它代表一組不同的肌動蛋白結合細胞骨架蛋白，包括血影蛋白、抗肌萎縮蛋白、肌營養相關蛋白和絲束蛋白。^[9]骨骼肌、心臟和平滑肌亞型定位於Z盤和類似的緻密體，它們有助於錨定肌原纖維肌動蛋白絲。α-肌動蛋白2已被證明與KCNA5、^[11]^[12]DLG1、^[11]DISC1、^[13]MYOZ1、^[14]GRIN2B、^[15]ADAM12、^[16]ACTN3、^[17]MYPN、^[18]PDLIM3、^[19]PKN、^[20]MYOT、^[21]TTN、^[22]NMDAR、^[23]SYNPO2、^[24]LDB3、^[25]和MYOZ1^[14]產生相互作用。

功能[編輯]

α-輔肌動蛋白2的主要功能是在Z盤上交聯絲狀肌動蛋白分子和來自相鄰肌小節的肌聯蛋白分子，該功能受磷脂調節。^[26]^[27]從漢普頓等人的研究中可以清楚地看出，這種交聯可以呈現多種構象，偏好60°和120°的角度。^[28]α-輔肌動蛋白2還在Z盤上的對接信號分子中發揮作用，另外的研究還表明α-輔肌動蛋白2與心臟離子通道的結合有關，尤其是K_v1.5。^[11]

臨床意義[編輯]

ACTN2的突變與肥厚型心肌病、^[29]擴張型心肌病和心內膜彈力纖維增生症有關。^[30]α-輔肌動蛋白2的不同功能反映在攜帶ACTN2突變的患者的不同臨床表現中。^[31]
