1B型活化素受體（Activin receptor type-1B），縮寫為ACVR1B或ALK-4，在人體中是一種由ACVR1B基因編碼的蛋白質^[5]^[6]。

ALK-4能夠對活化素或活化素樣配體（即抑制素）的信號進行轉導。活化素首先與ACVR2A（英語：ACVR2A）或ACVR2B（英語：ACVR2B）結合，之後再與ALK-4形成複合物。上述過程能夠招募R-SMAD（英語：R-SMAD）、SMAD2（英語：SMAD2）或者SMAD3（英語：SMAD3）分子^[7]。ALK-4也可以轉導NODAL（英語：NODAL）、GDF-1、Vg1的信號。但是，和活化素不同，這些分子（與ALK-4的結合）需要Cripto（英語：Cripto）蛋白等共受體^[8]。

功能

活化素是一類二聚體生長分化因子，屬於TGF-β蛋白質超家族，一類結構上相關的信號蛋白。活化素信號能夠通過一個包含至少兩分子1型以及兩分子2型受體的受體絲氨酸激酶異聚複合體進行轉導。這些受體都屬於跨膜蛋白，包含一個含有豐富半胱氨酸區域的細胞外配體結合結構域，一個跨膜結構域，以及一個推測具有絲氨酸或蘇氨酸專一性的細胞內（即細胞質中的）（激酶）結構域。1型受體對信號轉導來說是必要的，2型受體則對1型受體的表達以及配體的結合來說不可或缺。在配體結合後，1型受體以及2型受體能夠形成一個穩定的複合物，並使1型受體被2型受體磷酸化^[6]。

基因結構與表達

編碼ALK-4基因含有11個外含子。可變剪接以及Poly(A)（多聚腺嘌呤）尾巴的變化使該基因擁有多個轉錄本，目前已有3個轉錄本得到闡明，另外，此基因可能存在第四個包含8號外顯子，且8號外顯子與11號外顯子缺乏9號外顯子的轉錄本，但是這種轉錄本對應的mRNA還沒有得到確認^[6]。

相互作用

ALK能與ACVR2A、ACVR2B發生相互作用^[9]^[10]^[11]。
